资源简介：
Galaxies from COSMOS field; observations merged from DECam and VIRCAM (see Hartley+22, https://doi.org/10.1093/mnras/stab3055). Formatted for Red Dragon galaxy characterization algorithm (see Black+20, https://doi.org/10.1093/mnras/stac2052).
COSMOS_*.h5 give large datasets without redshift nor stellar mass cuts
DES_DEEP_smass*to*_Z3p5.h5 vet above griz dataset to a single mass decade, extending only out to redshift z=3.5
