Data

I am now incorporating the DES redMaGiC galaxy catalogue of luminous red galaxies. The number density maps will be made up of CMASS and redMaGiC galaxies. Figure 1 shows a ~200 Mpc slice at z~.55 with CMASS galaxies plotted in blue and redMaGiC in gray. The redMaPPer clusters which will be stacked are plotted in larger red circles. As expected, the clusters lie trace the redMaGiC galaxy distribution because the two samples are run with the same algorithm.

Trying eccentricity cuts. Start with lambda > 10 clusters (from Redmapper lambda-halo mass relation), 200 Mpc slice ~ z=0.55. Hessian orientation on 30 arcminutes of the full number density map from Peak Patch.

2258 clusters, no e cut.

2258 clusters, no e > 500.

2258 clusters, no e > 700.
