Parameters:
info : Table

Exposure information table with columns ‘FILE’ and ‘FILTER’.

output : str, None

Filename for output wcs reference image.

filters : list or None

List of filters to consider for the output mosaic. If None, then use all exposures in the info list.

pad_reference : float

Image padding, in arcsec.

pixel_scale : None or float

Pixel scale in in arcsec. If None, then the script computes automatically
