COSMOS Total Environment Catalog Definitions
Overview
All objects that are flagged as galaxies (type=0 in the COSMOS2015 catalog) and
are in the redshift range 0.1 < z < 1.2 are selected and interpolated to the
environment and cosmic web measurements of Darvish et al. (2017).
Note that no stellar mass or coordinate cuts are applied to this sample.
Please cite Darvish et al. 2017, ApJ, 837, 16 and Darvish et al. 2015, ApJ, 805, 121 if you use this catalog.
