As a result, there is a dearth of well-characterized solar analogs for observations in the near-infrared, a wavelength range important for studying solar system objects. We present 184 stars selected based on solar-like spectral type and V-J and V-K colors whose spectra we have observed in the 0.8-4.2{mu}m range for calibrating our asteroid observations. Each star has been classified into one of three ranks based on spectral resemblance to vetted solar analogs. Of our set of 184 stars, we report 145 as reliable solar-analog stars, 21 as solar analogs usable after spectral corrections with low-order polynomial fitting, and 18 as unsuitable for use as calibration standards owing to spectral shape, variability, or features at low to medium resolution. We conclude that all but five of our candidates are reliable solar analogs in the longer wavelength range from 2.5 to 4.2{mu}m. The average colors of the stars classified as reliable or usable solar analogs are V-J=1.148, V-H=1.418, and V-K= 1.491, with the entire set being distributed fairly uniformly in R.A. across the sky between -27{deg} and +67{deg} in decl.2020AJ....160..130Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/160/130CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/183 : UBVRI Photometric Standards (Landolt 1992)I/259 : The Tycho-2 Catalogue (Hog+ 2000)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)VI/19 : UBV Photoelectric Sequences in SA 92-115 (Landolt 1973)J/ApJ/555/932 : IR fluxes of solar-type stars (Spangler+, 2001)J/ApJ/705/89 : IRS spectra of solar-type stars (Lawler+, 2009)J/ApJS/181/62 : Survey of young solar analogs (Metchev+, 2009)J/ApJS/212/10 : WISE IR excesses for stars within 75pc (Patel+, 2014)J/A+A/587/A65 : Visible and near-infrared solar spectra (Reiners+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/160/130https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/160/130http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/160/130https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/160/130https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/160/130http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/160/130GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/160/130/table2 (Rankings for solar analog candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/160/130/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/160/130/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/160/130/table2?GETtext/xml+votable180.050000true2.10729176.61680560.005555555555555556Cone search capability for table J/AJ/160/130/table1 (Final set of 17 primary solar analogs)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/160/130/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/160/130/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/160/130/table1?GETtext/xml+votable180.050000true9.2327522.30358330.0055555555555555566/185 361 481 569 1167 1258 1531 1608 1633 1673 1682 1728 1978 2083 2111 2287 2497 2780 2919 2961 3154 4269 4360 4894 4906 5073 5327 5336 5704 6265 6721 7133 7836 7849 8282 8283 8286 8330 8400 8829 8975 9077 9114 9406 9492 10082 10804 11063 11303 11853 12477 12747 12885 12939 13016 13115 13348 13445 13503 13596 13598 13791 13806 13943 14349 14656 14889 14948 15174 15623 15881 16682 16806 17084 17335 17425 17462 17564 17817 17840 17970 18266 18489 18697 18779 18914 19093 19172 19282 19333 19388 19424 19491 19509 19619 19914 20049 20056 20129 20145 21061 21066 21099 21111 21511 21594 21775 22447 22484 22758 22779 22926 23228 23279 23282 23513 23545 23706 23943 24099 24155 24254 24256 24295 24341 24374 24454 24523 24542 24774 25300 25555 25586 26256 26440 26615 27752 27780 28386 28490 28871 28962 29127 29422 29591 29756 30043 30233 30357 30481 30540 31156 31334 31351 31382 31428 31796 31843 31886 32028 32069 32100 32128 32173 32288 32589 32751 36072 36794 40661 40932 42933 43876 44814 44865 44909 45051 48352 48470 48572 48865 48908 49114https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/160/130?format=asciiOpticalInfrareddefaultJ/AJ/160/130/table2Rankings for solar analog candidatesNameStar Namemeta.id;meta.maincharprimaryrecnoRecord number assigned by the VizieR team.
