Welcome to MAOPhot 1.0.0, a PSF Photometry tool using Astropy 6.0.0 and photutils.psf 1.10.0
This program was derived from MetroPSF by Maxym Usatov.
MAOPhot calculates stellar magnitudes from Fit (*.fit, *.fits, *.fts) formatted digital photographs using PSF photometry. It produces an extended AAVSO (American Association of Variable Star Observers) report which can be submitted to the AAVSO using their online tool WebObs (http://www.aavso.org/webobs).
MAOPhot uses the PSF (point spread function) Photometry method exclusively.
PSF modeling is well suited for measuring stellar magnitudes in crowded fields, or the magnitude of a star that has a close companion, e.g., Z Tau. (See https://www.aavso.org/lpv-double-trouble-campaign-0)
MAOPhot is written in Python using Astropy 
MAOPhot has been redesigned for AAVSO reporting only and includes, but not limited to the following enhancements:
o uses Astropy 6.0.0 and photutils.psf 1.10.0 (all packages required have version specified in requirements.txt file)
o generation of Effective PSF model (EPSF model), and ability to create a ‘rejection list’ of stars that the user can select that will not be part of the EPSF model
o option to use an Integrated Gaussian PRF (Pixel Response Function) as model
o PSF Photometry using an iterative algorithm to perform point spread function photometry
o PSF Photometry using a non-iterative algorithm to perform point spread function
o PSF Photometry using an ensemble of comparison stars or a single comp star
o generation of Two-Color Photometry (B, V), (V, R) or (V, I), and Single Image Photometry reports in AAVSO extended format
o use of telescope Transformation Coefficients (needed for Two Color Photometry)
o user can specify check star and list of comp stars to use
o a Radio Button option to display all AAVSO comp stars as AAVSO label numbers and any found VSX objects in image field or only VSX and AAVSO comp stars specified in settings
o intermediate results are saved as .csv files
o user can optionally enter a AAVSO Chart ID when retrieving comparison star data
o if intermediate results include found comp stars or VSX objects associated with an image being loaded, then these objects are displayed
