Problem & Solution Description (including issue #)

Code Quality

• My code follows the code style of this project
• I have written unit tests or justified all instances of #pragma: no cover; in the case of a bugfix, a new test that breaks as a result of the bug has been added
• My code contains relevant comments and necessary documentation for future maintainers; the change is reflected in applicable demos/tutorials (with output cleared!) and added/updated docstrings use the NumPy docstring format
• Any breaking changes, described above, are accompanied by backwards compatibility and deprecation warnings

There is one line that is not unit tested:

•     if pdf:
  

•         Vpdf=compute_pdfs_fit(photoz, photozerr, zgrid)
  

•     else:
  

•         Vpdf=None  
  

A fix would be

          Vpdf = None
          if pdf:
              Vpdf = compute_pdfs_fit(photoz, photozerr, zgrid)

Looks good, everything now works
