get_DC2_data(filters=['u', 'g', 'r', 'i', 'z', 'y'], tract=10054, patch=[0, 0], coord=None, cutout_size=[128, 128])[source]

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

  • cutout_size ([int, int]) – Size of cutout to use (set to None for no cutting). Default is [128, 128]

  • form (The image filepath is in the) – {dirpath}/deepCoadd/HSC-{filter}/{tract}/{patch[0]},{patch[1]}/calexp-HSC-{filter}-{tract}-{patch[0]},{patch[1]}.fits

Returns:

data – HSC data array with dimensions [filters, N, N]

Return type:

ndarray
