__init__(*args, **kwargs)[source]

Linear PSF photometry.

Do point spread function photometry with fixed centroids. The flux of all stars in the image are fitted simultaneously using a linear least squares method.

Note

Inspired by the psf_photometry class set up by Rasmus Handberg <rasmush@phys.au.dk>. The code in this __init__() function as well as the logging, catalog call, time domain loop structure, catalog star limits and lightcurve output is copied from that class.
