WebbWe apply the redMaPPer algorithm to 10, 000 deg 2 of SDSS DR8 data and present the resulting catalog of 25,000 clusters over the redshift range z ∈ [0.08, 0.55]. The redMaPPer photometric redshifts are nearly Gaussian, with a scatter σ z 0.006 at z 0.1, increasing to σ z 0.02 at z 0.5 due to increased photometric noise near the survey limit.
