[Bug] Mask stars to reduce contamination #254

Closed astrofoley closed 2 months ago

🐞 Bug Report

Describe the bug

There are occasionally stars that are in an aperture, which contaminate the photometry. The level of contamination depends on the properties of the star, the filter, the PSF, where it lands in the aperture, etc. It is possible to use a point-source catalog (say 2MASS) to determine the position of stars and mask them before doing photometry.


Is this a regression?

No
