Module Contents

gen_truthcats(pars)

Generates a truth catalog and writes it to a FITS file.

Parameters:

pars (list) – A 4-entry list of: * name : str or None * filter : str or int * input prefix : str * outstem : str

Returns:

• None

• [<name>, <filter>, <input prefix>, <outstem>]

Notes

If “name” is not None, then reads WCS from the output file. If “name” is None, then the WCS is generated internally. In this case, only the starting block output file needs to exist.

The “filter” should either be a letter (‘F’,’H’,’J’,…) or an integer (0,1,2,…) designation. If it is a letter, then you should still include it in the input file prefix.

If the outstem is ‘’, then the output file name is generated according to the configuration file.

gen_truthcats_from_cfg(cfg)

Usage from configuration file.
