Our goal is to facilitate the public use of the completed ALFALFA catalog by providing carefully determined matches to SDSS counterparts, including matches for ~10000 galaxies that do not have SDSS spectra. These identifications can provide a basis for further crossmatching with other surveys using SDSS photometric IDs as a reference point. We derive absolute magnitudes and stellar masses for each galaxy using optical colors combined with an internal reddening correction designed for small- and intermediate-mass galaxies with active star formation. We also provide measures of stellar masses and star formation rates based on infrared and/or ultraviolet photometry for galaxies that are detected by the Wide-field Infrared Survey Explorer and/or the Galaxy Evolution Explorer. Finally, we compare the galaxy population in the ALFALFA-SDSS sample with the populations in several other publicly available galaxy catalogs and confirm that ALFALFA galaxies typically have lower masses and bluer colors.</description><source format="bibcode">2020AJ....160..271D</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/160/271</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic service</relatedResource></relationship><relationship><relationshipType>IsServedBy</relationshipType><relatedResource>Conesearch service</relatedResource></relationship><relationship><relationshipType>related-to</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/II/363">II/363 : The band-merged unWISE Catalog (Schlafly+, 2019)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/VIII/65">VIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/VIII/77">VIII/77 : HI spectral properties of galaxies (Springob+, 2005)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/AJ/133/2569">J/AJ/133/2569 : Arecibo legacy fast ALFA survey III.
