COSMOS Mass Complete Environment Catalog Definitions

Overview

All objects that are flagged as galaxies (type=0 in the COSMOS2015 catalog), located in the range 149.33 < RA(deg)< 150.8, 1.6 < Dec(deg) < 2.83, are in the redshift range 0.1 < z < 1.2, and have stellar masses log(M*/Msun)≥9.6 (Chabrier IMF) are selected for environment and cosmic web measurements and they are presented here in this catalog. See Darvish et al. (2017) for details. Please cite Darvish et al. 2017, ApJ, 837, 16 and Darvish et al. 2015, ApJ, 805, 121 if you use this catalog.
