The SDSS DR16 / CatWISE2020 Spectro-Photometric Sample
Description
SDSS DR16 sources with clean (ZWARNING == 0) spectra are matched with CatWISE2020 sources and sources meeting the following criteria
dered_r > 12 && dered_r < 22 && dered_u != -9999.0 && dered_g != -9999.0 && dered_r != -9999.0 && dered_i != -9999.0 && dered_z != -9999.0 && w1mpro != 9999. && w2mpro != 9999. && w1snr > 5 && w2snr > 5 && blend_ext_flags == 1
have been retained. SDSS magnitudes are in the SDSS AB system, where CatWISE2020 magnitudes have been converted from the CatWISE2020 Vega system to the AB system.
The "small" and "large" versions contain the very same sample (i.e. rows) but a more limited and more extensive set of properties/features (i.e. columns) respectively.
