Abstract:
We present a catalog of galaxy cluster masses derived by exploiting
the tight correlation between mass and richness, i.e., a properly
computed number of bright cluster galaxies. The richness definition
adopted in this work is properly calibrated, shows a small scatter
with mass, and has a known evolution, which means that we can estimate
accurate (0.16dex) masses more precisely than by adopting any other
richness estimates or X-ray or SZ-based proxies based on survey data.
We measured a few hundred galaxy clusters at 0.05<z<0.22 in the
low-extinction part of the Sloan Digital Sky Survey footprint that are
in the 2015 catalog of Planck-detected clusters, that have a known
X-ray emission, that are in the Abell catalog, or that are among the
most most cited in the literature. The derived cluster mass values are
included in the distributed value-added cluster catalog of the 275
clusters with a derived mass larger than 1014M☉. A web
front-end is available at the URL

Description:
Table 1 provides refined cluster position, redshift,
cross-identification and more importantly mass of 275 galaxy clusters
with logn200>21.6 (logM200/M_☉>14) in the low-extinction part
of the SDSS footprint and with 0.05<z<0.22.
