cds-question@unistra.frsupernovaestellar-spectral-typesredshiftedinfrared-photometrysurveysSweetSpot is a 3 yr National Optical Astronomy Observatory (NOAO) survey program to observe Type Ia supernovae (SNe Ia) in the smooth Hubble flow with the WIYN High-resolution Infrared Camera (WHIRC) on the WIYN 3.5 m telescope. We present data from the first half of this survey, covering the 2011B-2013B NOAO semesters and consisting of 493 calibrated images of 74 SNe Ia observed in the rest-frame near-infrared (NIR) in the range 0.02<z<0.09. Because many observed supernovae require host-galaxy subtraction from templates taken in later semesters, this release contains only the 186 NIR (JHK_s_) data points for the 33 SNe Ia that do not require host-galaxy subtraction. The sample includes four objects with coverage beginning before the epoch of B-band maximum and 27 beginning within 20 days of B-band maximum. We also provide photometric calibration between the WIYN+WHIRC and Two Micron All-Sky Survey (2MASS) systems, along with light curves for 786 2MASS stars observed alongside the SNe Ia. This work is the first in a planned series of three SweetSpot Data Releases. Future releases will include the full set of images from all 3 yr of the survey, including host-galaxy reference images and updated data processing with host-galaxy reference subtraction. SweetSpot will provide a well-calibrated sample that will help improve our ability to standardize distance measurements to SNe Ia, examine the intrinsic optical-NIR colors of SNe Ia at different epochs, explore the nature of dust in other galaxies, and act as a stepping-stone for more distant, potentially space-based surveys.2018AJ....155..201Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/155/201CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/sn : Asiago Supernova Catalogue (Barbon et al., 1999-)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)J/ApJ/689/377 : SNe Ia as NIR standard candles from PAIRITELJ/ApJ/699/L139 : Spectral parameters of SNe Ia (Wang+, 2009)J/ApJ/700/331 : Light curves of type Ia supernovae (CfA3) (Hicken+, 2009)J/ApJ/700/1097 : Light curve parameters of SN Ia (Hicken+, 2009)J/A+A/523/A7 : Light curves of type Ia supernovae in SNLS (Guy+, 2010)J/ApJ/731/120 : Intrinsic SN Ia light curves (Mandel+, 2011)J/AJ/143/126 : Spectroscopy of 462 nearby Type Ia SNe (Blondin+, 2012)J/ApJS/200/12 : CfA4: light curves for 94 type Ia SNe (Hicken+, 2012)J/ApJS/213/19 : Optical and near-IR light curves of 64 SNe (Bianco+, 2014)J/ApJS/220/9 : CfAIR2: NIR light curves of Type Ia SNe (Friedman+, 2015)J/MNRAS/448/1345 : YJK for Type Ia supernovae (Dhawan+, 2015)J/AJ/154/211 : The CSP (DR3): photometry of low-z SNe IaJ/ApJ/848/56 : Relationships between SNe Ia and the host galaxieshttp://www.phyast.pitt.edu/~wmwv/SweetSpot/DR1_data/ : Processed data, stacks,https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/155/201https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/155/201http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/155/201https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/155/201https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/155/201http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/155/201GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/155/201/table4 (Persson photometric standard stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/155/201/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/155/201/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/155/201/table4?GETtext/xml+votable180.050000true151.620833341.02388890.005555555555555556Cone search capability for table J/AJ/155/201/SNIa (SN Ia properties from the literature (table 3) and 2MASS calibration stars (table 7))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/155/201/SNIa?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/155/201/SNIa?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/155/201/SNIa?GETtext/xml+votable180.050000true352.2278.914333330.0055555555555555566/221 635 675 1688 2169 2311 2440 2561 4288 5030 5115 5711 5766 6180 6726 6953 7014 7197 7297 8169 8532 8626 9322 9452 9530 9535 9736 10844 10867 10978 11042 11328 11434 11840 12380 12497 13523 13545 13694 16713 16756 17039 17671 17750 18009 18209 18258 19283 19421 19438 19490 19532 19617 19619 19994 20119 20356 21175 22875 22943 23113 23206 23215 23468 24926 24957 25051 25722 25770 25827 26125 26803 27738 27749 27914 28226 28599 34531 48922 490077.952274030004205e-20 1.7798557115773645e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/155/201?format=asciiInfrareddefaultJ/AJ/155/201/table4Persson photometric standard starsrecnoRecord number assigned by the VizieR team.
