Support for magnitude limits in Source files
Currently the Source file format supports storing magnitude bands as a FITS binary table with 3 columns:
- filter band
- magnitude
- magnitude error
It would be useful to also be able to assign magnitude limits, i.e. when an object is not detected in a particular band.
Perhaps two extra columns could be added:
- upper magnitude limit
- upper magnitude limit error
Since the default values should be NaN if not provided, I imagine it should be possible to retain some backward compatibility for reading older Source file versions.
