DWCal, or Delay-Weighted Calibration, is a new technique for precision interferometric calibration. To learn more about this approach, read Byrne 2022.
Run pip install -e . from the top-level directory.
- scipy
- pyuvdata
Check out tutorial.ipynb for an example of calibrating with and without delay weighting.
Sample simulated data is available as uvfits files in the dwcal/data/ directory.
data.uvfits contains visibilities simulated from a full sky catalog, and model.uvfits
contains visibilities simulated from an incomplete sky model. See Byrne 2022
for more details about these simulations and the calibration results.
