cds-question@unistra.frstar-forming-regionsradio-spectroscopyradio-astronomyOrion-KL is a well-known high-mass star-forming region that has long been the target of spectral line surveys and searches for complex molecules. One spectral window where the region had never been surveyed is around wavelengths of {lambda}=1 cm. This is an important window to observe, due to the fundamental and low energy transitions of numerous complex molecules that indicate the maximum spatial extent of the molecular species; knowing the spatial distribution of a molecule aids in determining the formation mechanism(s) of that molecule. Additionally, there are fewer transitions in this window, reducing confusion caused by blended lines that can be very problematic at shorter wavelengths ({lambda}<3 mm). In this work, we present the first spectral line survey at {lambda}=1 cm of the Orion-KL region. A total of 89 transitions were detected from 14 molecular species and isotopologues, and two atomic species. The observations were conducted with the Combined Array for Research in Millimeter-wave Astronomy in both interferometric and single dish modes.2017AJ....154..152Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/154/152CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/532/A32 : HCOOCH3 map of Orion-KL (Favre+, 2011)J/A+A/559/A51 : HC_3_N in Orion KL (Esplugues+, 2013)J/ApJ/779/119 : HCOOCH_2_D detection in Orion KL (Coudert+, 2013)J/ApJ/784/L7 : CH_3_CH_2_SH detection in Orion KL (Kolesnikova+, 2014)J/ApJS/215/25 : Methyl formate (HCOOCH3) observations (Favre+, 2014)J/A+A/581/A48 : 1.3cm line survey toward Orion KL (Gong+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/154/152https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/154/152http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/154/152https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/154/152https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/154/152http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/154/152GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/154/152/table1 (Description of Sources in Orion-KL)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/154/152/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/154/152/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/154/152/table1?GETtext/xml+votable180.050000true83.808775-5.372924440.0055555555555555566/21439https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/154/152?format=asciiMillimeterRadiodefaultJ/AJ/154/152/table3Molecular Parameters of Observed LinesrecnoRecord number assigned by the VizieR team.
