exception psfsubtraction.fitpsf.OptionalAttributeError[source] [edit on github]

Problem with optional attribute in the PSF fitter class.

Some functions require that more than the usual attributes image, image1d, psfbase, and psfbase1d are defined. These other attributes are optional in the sense that most fitter objects will not need them, but they might be required for e.g. certain optregion functions.
