make_dummy_catalog¶
- romanisim.catalog.make_dummy_catalog(coord, radius=0.1, rng=None, seed=42, nobj=1000, chromatic=True, galaxy_sample_file_name=None)¶
Make a dummy catalog for testing purposes.
- Parameters:
- coordgalsim.CelestialCoordinate
center around which to generate sources
- radiusfloat
radius (deg) within which to generate sources
- rngGalsim.BaseDeviate
Random number generator to use
- seedint
Seed for populating random number generator. Only used if rng is None.
- nobjint
Number of objects to simulate.
- chromaticbool
Use chromatic objects rather than gray objects. The PSF of chromatic objects depends on their SED, while for gray objects this dependence is neglected.
- Returns:
- list[CatalogObject]
list of catalog objects to render
