cds-question@unistra.frstandard-starsk-starsinfrared-photometrystellar-spectral-typesWe present 3.6 and 4.5{mu}m photometry for a set of 61 standard stars observed by Spitzer's Infrared Spectrograph (IRS). The photometry was obtained with the Infrared Array Camera (IRAC) on Spitzer in order to help tie the calibration of IRAC and the IRS, which had been anchored to the calibration of the Multiband Infrared Photometer for Spitzer. The wavelength range of the IRS data only slightly overlaps with the IRAC 4.5{mu}m band and not at all with the 3.6{mu}m band. Therefore, we generated synthetic spectra from spectral templates of stars with the same spectral types and luminosity classes as our sample stars, normalized to the IRS data at 6-7{mu}m, and compared those to the observed photometry. The new IRAC observations of IRS standard stars demonstrate that the two instruments are calibrated to within 1% of each other.2022AJ....164..161Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/164/161CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/pastel : The PASTEL catalogue (Soubiran+, 2016-)J/AJ/110/275 : IR spectra of standard stars (Cohen+ 1995)J/PASP/110/863 : A Stellar Spectral Flux Library; 1150 - 25000 A (Pickles 1998)J/AJ/132/1445 : Standard calibration stars infrared spectra (Engelke+, 2006)J/AJ/135/2245 : Absolute spectrum of Sun and Vega for 0.2-30um (Rieke+, 2008)J/AJ/149/11 : Spectra of candidate standard stars in mid-IR (Sloan+, 2015)J/AJ/161/177 : Spitzer IRAC photo of 36 JWST calibration stars (Krick+, 2021)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/164/161https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/164/161http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/164/161https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/164/161https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/164/161http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/164/161GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/164/161/table1 (*Observations: A dwarfs and solar analogs)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/164/161/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/164/161/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/164/161/table1?GETtext/xml+votable180.050000true284.6157083-52.93863890.005555555555555556Cone search capability for table J/AJ/164/161/table2 (*Observations: K giants)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/164/161/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/164/161/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/164/161/table2?GETtext/xml+votable180.050000true179.2257917-0.503750.005555555555555556Cone search capability for table J/AJ/164/161/table3 (Observed Photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/164/161/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/164/161/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/164/161/table3?GETtext/xml+votable180.050000true284.6156964-52.93862830.0055555555555555566/6940 7239 10110 10197 10217 11416 11423 11553 11734 11927 12255 12915 12918 14126 14662 15096 15153 15289 15291 15323 15327 15348 16031 18463 22463 23426 25116 26965 29199 30043 30359 32838 33193 33203 33351 33562 33794 33814 33875 33880 34240 37039 37164 37423 37428 37435 37520 37544 37546 38920 38924 39078 40892 43233 43539 46982 47095 47298 47442 49049https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/164/161?format=asciiInfrareddefaultJ/AJ/164/161/table1*Observations: A dwarfs and solar analogsSpTypeSpectral Typesrc.spTypecharAOR[58130432/68759040] AOR Keymeta.id;obsintObsObservation Date; yeartime.epoch;obsrecnoRecord number assigned by the VizieR team.
