Get HSC data given tract/patch info or SkyCoord

Parameters:

dirpath (str) – Path to HSC image file directory
filters (list) – A list of filters for your images. Default is [‘g’, ‘r’, ‘i’].
tract (int) – An integer used for specifying the tract. Default is 10054|
patch ([int, int]) – Patch #,#. Default is [0,0]
coord (SkyCoord) – Astropy SkyCoord, when specified, overrides tract/patch info and attempts to lookup HSC filename from ra, dec. Default is None
