VizieR Online Data Catalog: NGC3627S and NGC3627N CO(1-0) data cubes (Beuther+, 2017)
Abstract
Paladino et al. (2008A&A...485..679P) present the PdBI for the first time, however, they focus on the CO(1-0) observations and do not complement the data with short spacing information. The PdBI observations were carried out on March 20, 2005 with 6 antennas in the C configuration. At that time, 1.3 and 2.6mm data could be taken simultaneously, and the observations targeted the CO(1-0) and (2-1) lines, respectively. The two frequencies were centered at 114.997 and 229.88GHz which are the transition rest frequencies at an assumed vlsr of ~712.6km/s. With four overlapping 160MHz spectral units, the correlator covered 580MHz for each line (corresponding to 1512 and 756km/s for the (1-0) and (2-1) lines, respectively). Bandpass and flux calibration were conducted with 1055+018 and MWC349, and the gains were calibrated with regular observations of 1116+128.
To complement the PdBI CO(2-1) data with the missing short spacing information, we used the IRAM 30m single-dish observations from the HERACLES survey (Leroy et al., 2009AJ....137.4670L). These data are available for download at www.mpia.de/HERACLES. The HERACLES CO(2-1) data were further processed in GILDAS/CLASS and finally combined and imaged with the PdBI data within the mapping part of the GILDAS package. (2 data files).- Publication:
