I'm ready to move on to more "advanced" research tools
A discussion of what photometry is and why you would want to do it. Includes where to find already-reduced Spitzer photometry.
If you've done photometry before and expect to do it the same way here, BE CAREFUL because IT WILL NOT WORK. The units of Spitzer images can be tricky. This page has a lot of information about these units and how to convert them into more familiar units.
A general discussion of color-magnitude and color-color plots.
A general discussion of spectral energy distribution (SED) plots.
Mosaicking - simple (more than 1 AOR from pbcd prod)
need example using regular photos
