The photometrically selected cluster sample, known as MaxBCG, includes ∼130000 objects between redshift 0.1 and 0.3, ranging in size from small groups to massive clusters. We split the clusters into bins of richness and luminosity and stack the surface density contrast to produce mean radial profiles. The mean profiles are detected over a range of scales, from the inner halo (25kpc/h) well into the surrounding large-scale structure (30Mpc/h), with a significance of 15 to 20 in each bin. The signal over this large range of scales is best interpreted in terms of the cluster-mass cross-correlation function. We pay careful attention to sources of systematic error, correcting for them where possible. The resulting signals are calibrated to the ∼10% level, with the dominant remaining uncertainty being the redshift distribution of the background sources.Description: The clusters used in this study are drawn from a superset of the recently released MaxBCG catalog of Koester et al. (2007, Cat. J/ApJ/660/239, 2007ApJ...660..221K). The galaxies used for cluster selection and shear measurement were drawn from the SDSS. The area used for this study is somewhat smaller than the SDSS data release 4 (Adelman-McCarthy et al. 2006, Cat. II/267; superseded by Cat. II/294).File Summary:
