Final Cluster "workflow map":

1. Look at the redshifts for all SDSS objects projected within 30 arcmin of the cluster center. Find the cluster redshift range visually, then work out the average redshift for all objects in that redshift range. That's your cluster redshift. Use astropy to work out the angular size that corresponds to a 1 Mpc radius at that redshift.

2. Make a cluster color magnitude diagram for all SDSS objects projected within 1 Mpc of the cluster center. On your plot, using different marker styles/colors, plot:

3. Overplot on that cluster CMD all Chandra X-ray sources that are:

4. For each X-ray source matched to an SDSS optical source brighter than r=20.5,

Overarching question: Are we finding cluster AGN? If so, what can we say about their properties, or how they might be triggered? What kind of follow-up studies might be interesting? What would you hope to learn? What additional data would you need?
