The SDSS DR16 / CatWISE2020 Spectro-Photometric Sample

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.
