romanisim.catalog.make_cosmos_galaxies(coord, radius=0.1, bandpasses=None, rng=None, seed=50, filename=None, cat_area=None, **kwargs)

Make a catalog of galaxies from sources in the COSMOS catalog. https://cosmos2020.calet.org/

Parameters:

coordastropy.coordinates.SkyCoord

Location around which to generate sources.

radiusfloat

Radius in degrees in which to uniformly generate sources.

bandpasseslist[str]

List of names of bandpasses in which to generate fluxes.

rnggalsim.BaseDeviate

Random number generator to use.

seedint

Seed to use for random numbers, only used if rng is None.

filenamestring

Optional filename of a catalog of galaxies to draw from. Code assumes a format similar to that of COSMOS.

cat_areafloat

Area of catalog file in square degrees.

Returns:

catalogastropy.Table

Table for use with table_to_catalog to generate catalog for simulation.
