An alternative to opencosmo package, tested to access diffsky catalogs on NERSC. I wrote this test to independently validate the galaxy samples obtained from opencosmo. The access to all the diffsky catalogs at NERSC is set by the path given in the code. One can edit the path in the code and apply to any other catalog in principle. Features: * Modify the 'cuts' function to include any additional cuts on the galaxy sample. * Save the filtered catalog in hdf5 format.

This is an independent implementation to access all the diffsky files at the path given in the code. One can edit the path in the code and apply it to any other catalog in principle.
Modify the cuts function to include any additional cuts on the galaxy sample.
The resulting sample is not saved yet. But it should be easy to implement in any format (parquet/hdf5/pandas etc).
