Photometry is the quantitative measure of brightness of an object in an astronomical images.
Most coherent, developed, tested materials
Movie (10:50) on Photometry, part of the "Filters, Magnitudes, Colors, Oh My!" playlist -- Dr. Luisa Rebull, 2020
Photometry overview -- Dr. Luisa Rebull (2010?)
Somewhat less coherent (or less standalone) materials
Aperture Photometry Overview -- Dr. Luisa Rebull (2010?)
PSF photometry - To come. Basic steps are essentially the same (detect objects, center up, determine what is background/source, sum up light for the source, check your results). More complicated than aperture photometry because you have many more free parameters than for aperture photometry.
need to add document i made for olivia and tom 2019
Other sources of interest
- Your local astronomy textbook or (if neccessary) the Wikipedia entry for photometry is probably a good place to go for a longer general introduction.
- The IRAF manuals are old but still very, very valid. If you can pay attention to the concepts and ignore the IRAF-specific instructions, you can learn an awful lot from these manuals. Oldies but goodies.
