−	* (this is cross-posted in 'concept' and 'skill' for Photometry) In 2019, an alumni team (Olivia Kuper and Tom Rutherford) were trying to carry our original photometry on Herschel images further. We had sources clumped close together on the sky, and even though aperture photometry was ok for our original project, they were trying to learn how to do PSF photometry in Python. They were struggling with vast array of free parameters. I wrote this [[Photometry Scaffolding]] document in an effort to help them understand, in words, what the free parameters were and why they mattered. This may or may not be useful for anyone else, but as I put a lot of time into it, I thought I'd post it here. -- Dr. Luisa Rebull, 2019	+	(this is cross-posted in 'concept' and 'skill' for Photometry) In 2019, an alumni team (Olivia Kuper and Tom Rutherford) were trying to carry our original photometry on Herschel images further.
