Regions of Bad Photometry

-Eli Rykoff

Brad Benson looked at SPT S/N for all the redMaPPer (v5.7) clusters in the SPT region. He noticed there was a class of high richness clusters with no SPT signal. What's up with that?

The bad clusters

These are riz color composite images of the bad clusters. Note that all of them are junk regions due to scattered light!
