VizieR Online Data Catalog: KEYSTONE: ammonia structures in Galactic GMCs (Keown+, 2019)
Abstract
Data were obtained as part of the K-band Focal Plane Array (KFPA) Examinations of Young STellar Object Natal Environments (KEYSTONE) survey, a large project on the Green Bank Telescope (GBT) that mapped NH3, HC5N, HC7N, HNCO, H2O, CH3OH, and CCS emission across 11 giant molecular clouds (Cygnus X North, Cygnus X South, M16, M17, Mon R1, Mon R2, NGC 2264, NGC 7538, Rosette, W3, and W48) at distances between 0.9 and 3kpc. Observations were conducted between 2016 October and 2019 March for a total of 356.25 observing hours, including overheads. Observations were made with the GBT's KFPA, which has seven beams arranged in the shape of a hexagon with beam centers separated by ~95" on the sky. See Section 2.2.
Herschel Level 2.5 data products at 70, 160, 250, 350, and 500um for each KEYSTONE region were downloaded from the European Space Agency Herschel Science Archive. See Section 2.3. C18O (3-2) data cubes observed by the HARP-ACSIS spectrometer on the James Clerk Maxwell Telescope (JCMT) were obtained from the JCMT Science Archive. See Section 2.4. (4 data files).- Publication:
