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 <em>griz</em> dataset to a single mass decade, extending only out to redshift z=3.5 Summary of dataset parameters Field Description AGE Gyr; age of galaxy DEC degrees; declination RA degrees; right ascension SSFR 1/yr; specific star formation rate Z redshift Z_err uncertainty estimated for redshift bands mag; photometric bands: [g, r, i, z] or [u, g, r, i, z, J, H, Ks] for ALL bands_err mag; uncertainty estimate for photometry smass dex; log stellar mass: log10(galactic stellar mass / 1 solar mass) smass_err dex; uncertainty estimate for lg mass
