With four projected aperture radii (10, 30, 50, 100 -kpc), we then have twelve sets of projected aperture quantities for each -(sub-)halo. Projected aperture quantities are stored in a group named -``ProjectedAperture/XXXkpc/projP``, where ``XXX`` is the corresponding -aperture radius, and ``P`` corresponds to a particular projection -direction (``x``, ``y`` or ``z``). - -Spherical overdensity properties (SO) -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - -are fundamentally different from the three other types in that their -aperture radius is determined from the density profile and is different -for different halos. They always include all particles within a sphere -around the centre of potential, regardless of halo membership. The -radius is either the radius at which the density reaches a certain -target value (50 crit, 100 crit, 200 crit, 500 crit, 1000 crit, 2500 -crit, 200 mean, BN98) or a multiple of such a radius (5xR 500 crit). -Details of the spherical overdensity calculation are given at the end of -this document. Spherical overdensities are only computed for centrals, -i.e. field halos. The inclusive sphere quantities are stored in a group -``SO/XXX``, where ``XXX`` can be either ``XXX_mean`` for density -multiples of the mean density, ``XXX_crit`` for density multiples of the -critical density, ``BN98`` for the overdensity definition of Bryan & -Norman (1998), and ``YxR_XXX_ZZZ`` for multiples of some other radius -(e.g. ``5xR_2500_mean``). The latter can only be computed after the -corresponding density multiple SO radius has been computed. This is -achieved by ordering the calculations. - -InputHalos -^^^^^^^^^^ - -Some properties are directly copied from the original halo catalogue -that was passed to SOAP. These are stored in a separate group, -``InputHalos``. - -SOAP -^^^^ - -Some properties are computed by SOAP using the other halo properties -present in the catalogue. These are stored in a separate group, -``SOAP``. This is just done for convenience; these quantities can be -computed from the SOAP output alone. - -The table below lists -^^^^^^^^^^^^^^^^^^^^^ - -all the groups in the output file which containing datasets. Note that -there will be three groups (``x``, ``y`` or ``z``) for each -``ProjectedAperture`` variation. Each halo variation can have a filter -applied to it. If a halo does not satisfy the filter then the variation -will not be calculated for that halo. More information on filters can be -found in the next section. - - -+------------------------------------+----------------------------------------+------------+-------------+ -| Group name (HDF5) |

subhalo contains sufficient -particles. Halo finders are often run with a configuration that requires -at least 20 particles for a satellite subhalo. However, even for those -particle numbers, a lot of the properties computed by SOAP will be zero -(e.g. the gas mass within a 10 kpc aperture), or have values that are -outliers compared to the full halo population because of undersampling. -We can save a lot of disk space by filtering these out by applying -appropriate cuts. Filtering means setting the value of the property to -``NaN``; HDF5 file compression then very effectively reduces the data -storage required to store these properties, while the size of the arrays -that the end user sees remains unchanged. Evidently, we can also save on -computing time by not computing properties that are filtered out. - -Since different properties can have very different requirements, -filtering is done in categories, where each category corresponds to a -set of quantities that are filtered using the same criterion. Inclusive, -exclusive or projected quantities with different aperture radii (or -overdensity criteria) can be used to create profiles. In order for these -profiles to make sense, we have to apply a consistent cut across all the -different aperture radii (or overdensity criteria) for the same subhalo -property type. Or in other words: the quantities for an inclusive sphere -with a 10 kpc aperture radius will use the same filter mask as the -quantities of the inclusive sphere with a 3000 kpc aperture radius, even -though the latter by construction has many more particles. - -Basic quantities (basic) -^^^^^^^^^^^^^^^^^^^^^^^^ - -are never filtered out, and hence are calculated for all objects in the -input halo catalogue. - -General quantities (general) -^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - -use a filter based on the total number of particles bound to the -subhalo. - -Gas quantities (gas) -^^^^^^^^^^^^^^^^^^^^ - -use a filter based on the number of gas particles bound to the subhalo. - -DM quantities (dm) -^^^^^^^^^^^^^^^^^^ - -use a filter based on the number of DM particles bound to the subhalo. - -Stellar quantities (star) -^^^^^^^^^^^^^^^^^^^^^^^^^ - -use a filter based on the number of star particles bound to the subhalo. - -Baryon quantities (baryon) -^^^^^^^^^^^^^^^^^^^^^^^^^^ - -use a filter based on the number of gas and star particles bound to the -subhalo. - -Note that there are no quantities that use a BH or neutrino particle -number filter. - -The particle number thresholds are set in the parameter file. The -different categories are summarised in the table below. - -+---------+-----------------------------------------------------------------------+ -| Name | criterion | -+=========+=======================================================================+ -| basic | (all halos) | -+---------+-----------------------------------------------------------------------+ -| general | :math:`N_{\rm{}gas}+N_{\rm{}dm}+N_{\rm{}star}+N_{\rm{}BH} \geq{} 100` | -+---------+-----------------------------------------------------------------------+ -| gas | :math:`N_{\rm{}gas} \geq{} 100` | -+---------+-----------------------------------------------------------------------+ -| dm | :math:`N_{\rm{}dm} \geq{} 100` | -+---------+-----------------------------------------------------------------------+ -| star | :math:`N_{\rm{}star} \geq{} 100` | -+---------+-----------------------------------------------------------------------+ -| baryon | :math:`N_{\rm{}gas}+N_{\rm{}star} \geq{} 100` | -+---------+-----------------------------------------------------------------------+ - -Overview table --------------- - -The table below lists all the properties that are computed by SOAP when -run in HYDRO mode. For dark matter only (DMO) mode only the properties -colored violet/purple are computed. This table is automatically -generated by SOAP from the source code, so that all names, types, units, -categories and descriptions match what is actually used and output by -SOAP. For each quantity, the table indicates for which halo types the -property is computed. Superscript numbers refer to more detailed -explanations for some of the properties and match the numbers in the -next section. If swiftsimio has been used to load a catalogue then the -fields names are in snake_case rather than CamelCase, e.g. -``CentreOfMass`` becomes ``centre_of_mass``. - -Note that quantities are given in the base units of the simulation -snapshot. The attributes of each SOAP dataset contains all the relevant -meta-data to convert between physical and co-moving units, i.e. -information about how the quantity depends on the scale-factor, and what -the conversion factor to and from CGS units is. All quantities are -:math:`h`-free. The conversion of the base units to CGS is given by: - -==== ============== -Unit CGS conversion -==== ============== -L 3.086e+24 cm -M 1.988e+43 g -t 3.086e+19 s -T 1 K -==== ============== - -For example, a property whose units are listed as M/t will have units of -velocity, where :math:`1 \, \rm{M/t} = 1\, \rm{km/s}`.

The approach we use is different -from that taken by VR, where both the mass and the radius are obtained -from independent interpolations on the mass and density profiles (the -latter uses the logarithm of the density in the interpolation). The VR -approach is inconsistent, in the sense that the condition - -.. math:: - - \begin{equation} - \frac{4\pi{}}{3} R_{\rm{}SO}^3 \rho{}_{\rm{}target} = M_{\rm{}SO},\label{eq:MSO_condition} - \end{equation} - -is not guaranteed to be true, and will be especially violated for large -radial bins (the bins are generated from the particle radii by sorting -the particles, so we have no control over their width). We instead opt -to guarantee this condition by only finding :math:`R_{\rm{}SO}` or -:math:`M_{\rm{}SO}` by interpolation and using eq. -(`[eq:MSO_condition] <#eq:MSO_condition>`__) to derive the other -quantity. - -.. container:: float - :name: fig:MSO_vs_RSO - - |image| |image1| - -While the interpolation of the logarithmic density profile to find -:math:`R_{\rm{}SO}` is more straightforward, we found that it can lead -to significant deviations between the value of :math:`M_{\rm{}SO}` and -the cumulative mass in neighbouring bins that can be more than one -particle mass, as illustrated in Fig. `1 <#fig:MSO_vs_RSO>`__. The -reason for this is that the cumulative mass profile at fixed density -increases very steeply with radius, so that a small difference in -:math:`R_{\rm{}SO}` leads to a relatively large difference in -:math:`M_{\rm{}SO}`. Conversely, fixing :math:`M_{\rm{}SO}` will lead to -an :math:`R_{\rm{}SO}` that only deviates a little bit from the -:math:`R_{\rm{}SO}` found by interpolating the density profile. However, -doing so requires us to find the intersection of the cumulative mass -profile at fixed density (green line in Fig. `1 <#fig:MSO_vs_RSO>`__) -with the actual cumulative mass profile, which means solving the -following equation: - -.. math:: - - \begin{equation} - \frac{4\pi{}}{3} \rho{}_{\rm{}target} R_{\rm{}SO}^3 = M_{\rm{}low} + \left( \frac{M_{\rm{}high}-M_{\rm{}low}}{R_{\rm{}high} - R_{\rm{}low}} \right) \left(R_{\rm{}SO} - R_{\rm{}low}\right), - \label{eq:RSO} - \end{equation} - -where :math:`R/M_{\rm{}low/high}` are the bounds of the intersecting bin -(which we find in the density profile). This third degree polynomial -equation has no unique solution, although in practice only one of the -three possible complex solutions is real. We find this solution by using -a root finding algorithm within the intersecting bin (we use Brent’s -method for this). - -For clarity, this is the full set of rules for determining the SO radius -in SOAP: - -#. Sort particles according to radius and construct the cumulative mass - profile. - -#. Discard any particles at zero radius, since we cannot compute a - density for those. The mass of these particles is used as an - :math:`r=0` offset for the cumulative mass profile. Since the centre - of potential is the position of the most bound particle, there should - always be at least one such particle. - -#. Construct the density profile by dividing the cumulative mass at - every radius by the volume of the sphere with that radius. - -#. Find intersection points between the density profile and the target - density, i.e. the radii :math:`R_{1,2}` and masses :math:`M_{1,2}` - where the density profile goes from above to below the threshold: - - #. If there are none, analytically compute - :math:`R_{\rm{}SO}=\sqrt{3M_1/(4\pi{}R_1\rho_{\rm{}target})}`, - where :math:`R_1` and :math:`M_1` are the first non zero radius - and the corresponding cumulative mass. This is a special case of - Eq. (`[eq:RSO] <#eq:RSO>`__). Unless there are multiple particles - at the exact centre of potential position, this radius estimate - will then be based on just two particles. - - #. In all other cases, we use :math:`R_{1,2}` and :math:`M_{1,2}` as - input for Eq. (`[eq:RSO] <#eq:RSO>`__) and solve for - :math:`R_{\rm{}SO}`. The only exception is the special case where - :math:`R_1 = R_2`. If that happens, we simply move further down - the line until we find a suitable interval. - -#. From :math:`R_{\rm{}SO}`, we determine :math:`M_{\rm{}SO}` using Eq. - (`[eq:MSO_condition] <#eq:MSO_condition>`__). - -Neutrinos – if present in the model – are included -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - -in the inclusive sphere calculation (and only here, since neutrino -particles cannot be bound to a halo) by adding both their weighted -masses (which can be negative), as well as the contribution from the -background neutrino density. The latter is achieved by explicitly adding -the cumulative mass profile at constant neutrino density to the total -cumulative mass profile before computing the density profile. This is -the only place where neutrinos explicitly enter the algorithm, except -for the neutrino masses computed for the SOs. Neutrinos are not included -in the calculation of the centre of mass and centre of mass velocity. - -Group membership files ----------------------- - -Before SOAP can be run we generate a set of files which contain halo -membership information for each particle in the SWIFT snapshot. The -datasets in these files are stored in the same order and with the same -partitioning between files as the datasets in the snapshots. This allows -SOAP to read halo membership information for sub-regions of the -simulation volume without reading the full halo-finder output. These -files may also be useful for visualising the input halo catalogue. - -The group membership files are HDF5 files with one group for each -particle type, named PartType0, PartType1, ... as in the snapshots. Each -group contains the following datasets: - -#. ``GroupNr_bound``: for each particle in the corresponding snapshot - file this contains the array index of the subhalo which the particle - is bound to. If a particle is not bound to any subhalo it will have - ``GroupNr_bound``\ =-1. - -#. ``Rank_bound``: the ranking by total energy of this particle within - the subhalo it belongs to, or -1 if the particle is not bound to any - subhalo. The particle with the most negative total energy has - ``Rank_bound``\ =0. - -#. ``GroupNr_all``: (VELOCIraptor only) for each particle in the - corresponding snapshot file this contains the array index of the VR - group which the particle belongs to, regardless of whether it is - bound or unbound. Particles in no group have ``GroupNr_all``\ =-1. - -#. ``FOFGroupIDs``: the 3D FOF group the particle is part of. This field - is only present if a FOF snapshot is listed in the parameter file. - This field is present in the snapshots themselves, but for FLAMINGO - hydro simulations the FOF was regenerated. If this field is present - it will overwrite the value from the snapshots when SOAP is run. - -The GroupNr values stored here are zero based array indexes into the -full subhalo catalogue, and not the subhalos IDs. For example the first -group in the VELOCIraptor catalogue has GroupNr=0 and ID=1. - -The script ‘make_virtual_snapshot.py‘ will combine snapshot and group -membership files into a single virtual snapshot file. This virtual file -can be read by swiftsimio and gadgetviewer to provide halo membership -information alongside other particle properties.
