cds-question@unistra.frmolecular-cloudsspectroscopyradial-velocityWe present a new multi-pixel high resolution (R>~10^7^) spectrometer for the Stratospheric Observatory for far-infrared astronomy (SOFIA). The receiver uses 2x7-pixel subarrays in orthogonal polarization, each in an hexagonal array around a central pixel. We present the first results for this new instrument after commissioning campaigns in May and December 2015 and after science observations performed in May 2016. The receiver is designed to ultimately cover the full 1.8-2.5THz frequency range but in its first implementation, the observing range was limited to observations of the [CII] line at 1.9THz in 2015 and extended to 1.83-2.07THz in 2016. The instrument sensitivities are state-of-the-art and the first scientific observations performed shortly after the commissioning confirm that the time electronic efficiency for large scale imaging is improved by more than an order of magnitude as compared to single pixel receivers. An example of large scale mapping around the Horsehead Nebula is presented here illustrating this improvement. The array has been added to SOFIA's instrument suite already for ongoing observing cycle 4.2016A&A...595A..34Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/595/A34CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/494/977 : HCO mapping of the Horsehead (Gerin+, 2009)J/A+A/560/A73 : Horsehead H_2_CO and CH_3_OH 30m and PdBI maps (Guzman+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/595/A34https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/595/A34http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/595/A34https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/595/A34https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/595/A34http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/595/A34GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/595/A34/list (Information on data cube)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/595/A34/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/595/A34/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/595/A34/list?GETtext/xml+votable180.050000true85.15724-2.413090.0055555555555555566/22854https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/595/A34?format=asciiOpticaldefaultJ/A+A/595/A34/listInformation on data cubeTitleTitle of the FITS filemeta.title;meta.fitscharsizeSize of FITS fileKibytephys.size;meta.fitsintFileNameName of FITS filemeta.id;meta.fitscharrecnoRecord number assigned by the VizieR team.
