RubinDirectoryCollection

class toasty.collection.RubinDirectoryCollection(dirname, unit=None)

Bases: ImageCollection

Load up imagery from a directory containing FITS files capturing a Rubin Observatory tract.

The directory will be searched for files whose names end in .fits. In each of those files, the HDUs beyond the first will be treated as separate science images that should be individually loaded. The images will be trimmed according to their DATASEC specification before being returned.

This class requires the ccdproc package to trim FITS CCD datasets.
