imutil.ccdops.trim_overlap

imutil.ccdops.trim_overlap(inputs, extension=None, coordinate='image')

Trim only the overlapping regions of the two CCDs

Parameters

coordinate : str, optional. = 'image'

Ways to find the overlapping region. If 'image' (default), output size will be np.min([ccd.shape for ccd in ccds], axis=0). If 'physical', overlapping region will be found based on the physical coordinates. Default: 'image'.

extension : int, str, (str, int), optional. = None

The extension of FITS to be used. It can be given as integer (0-indexing) of the extension, EXTNAME (single str), or a tuple of str and int: (EXTNAME, EXTVER). If None (default), the first extension with data will be used. Default: None.

Notes

~astropy.wcs.WCS is not acceptable because no rotation/scaling is supported.
