The survey covers 54.64deg^2^ in a 1.5{deg} wide strip across the northern sky centered at a decl. of 43.25{deg}. We report the redshift, the spectral indicator Dn4000, and the stellar mass. The red-selected survey is 81% complete for 55,962 galaxies with (g-r)&gt;1 and r&lt;20.5; it is 72% complete for 32,908 galaxies with (g-r)&gt;1, (r-i)&gt;0.5 and 20.5&lt;r&lt;21.3. Comparison of the survey basis SDSS photometry with the HSC-SSP photometry demonstrates that HectoMAP provides complete magnitude-limited surveys based on either photometric system. We update the comparison between the HSC-SSP photometric redshifts with HectoMAP spectroscopic redshifts; the comparison demonstrates that the HSC-SSP photometric redshifts have improved between the second and third data releases. HectoMAP is a foundation for examining the quiescent galaxy population (63% of the survey), clusters of galaxies, and the cosmic web. HectoMAP is completely covered by the HSC-SSP survey, thus enabling a variety of strong- and weak-lensing investigations.</description><source format="bibcode">2023ApJ...945...94S</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/945/94</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/VII/203">VII/203 : Las Campanas Redshift Survey (Shectman+ 1996)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/V/154">V/154 : Sloan Digital Sky Surveys (SDSS), Release 16 (DR16) (Ahumada+, 2020)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/AJ/139/1857">J/AJ/139/1857 : Sample of major galaxy pairs at z=0.08-0.38 (Woods+, 2010)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJS/200/8">J/ApJS/200/8 : AGES: the AGN and Galaxy Evolution Survey (Kochanek+, 2012)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJ/750/168">J/ApJ/750/168 : Redshift survey in Subaru GTO2deg^2^ field (Kurtz+, 2012)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJS/213/35">J/ApJS/213/35 : SHELS: complete galaxy z survey for R&lt;=20.6 (Geller+, 2014)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/MNRAS/452/2087">J/MNRAS/452/2087 : Galaxy And Mass Assembly (GAMA): DR2 (Liske+, 2015)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJS/224/11">J/ApJS/224/11 : SHELS: redshift survey of the F1 DLS field (Geller+, 2016)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJ/819/63">J/ApJ/819/63 : Hectospec survey of SZ clusters (HeCS-SZ) (Rines+, 2016)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJS/224/1">J/ApJS/224/1 : redMaPPer cluster catalog from DES data (Rykoff+, 2016)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJS/229/20">J/ApJS/229/20 : MMT/Hectospec redshift survey for Abell 2029 (Sohn+, 2017)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJS/234/21">J/ApJS/234/21 : hCOSMOS: Hectospec survey of COSMOS gal.
