Abundances and atmospheric parameters were derived using infrared spectra from CSHELL on the NASA Infrared Telescope Facility and from optical echelle spectra. We measured Cl abundances by fitting a H^35^Cl molecular feature at 3.6985{mu}m with synthetic spectra. We also measured the abundances of O, Ca, Ti, and Fe using atomic absorption lines. We find that the [Cl/Fe] ratio for our stars agrees with chemical evolution models of Cl, and the [Cl/Ca] ratio is broadly consistent with the solar ratio over our metallicity range. Both indicate that Cl is primarily made in core-collapse supernovae with some contributions from Type Ia supernovae. We suggest that other potential nucleosynthesis processes, such as the {nu}-process, are not significant producers of Cl. Finally, we also find our Cl abundances are consistent with HII and planetary nebular abundances at a given oxygen abundance, although there is scatter in the data.2021AJ....161..183Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/161/183CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)I/345 : Gaia DR2 (Gaia Collaboration, 2018)J/A+A/508/355 : Scaled solar tracks and isochrones (Bertelli+, 2009)J/ApJ/711/619 : {alpha}-element abundances in galactic PNe (Milingo+, 2010)J/MNRAS/427/343 : IR excesses of Hipparcos stars (McDonald+, 2012)J/ApJ/764/78 : Oxygen abundances in nearby FGK stars (Ramirez+, 2013)J/A+A/562/A71 : Chemical abund. solar neighbourhood dwarfs (Bensby+, 2014)J/A+A/629/A128 : Spectra of molecular absorbers (Wallstrom+, 2019)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/161/183https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/161/183http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/161/183https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/161/183https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/161/183http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/161/183GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/161/183/table1 (and observation summary)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/161/183/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/161/183/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/161/183/table1?GETtext/xml+votable180.050000true13.388906448.51885690.0055555555555555566/196 2858 3203 5574 5647 8573 8762 9030 9153 9245 9435 9441 9578 9818 9838 9964 10737 10840 11594 12900 13089 14753 14765 14905 14917 14924 14952 15006 15243 22994 23422 23469 24207 26415 26423 26578 27687 28050 28649 31629 31682 31923 31990 31996 32123 32170 32190 32308 32414 32519 326527.952274030004205e-20 1.0188844282367877e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/161/183?format=asciiOpticalInfrareddefaultJ/AJ/161/183/table1and observation summaryrecnoRecord number assigned by the VizieR team.
