Based on observations carried out with the IRAM Plateau de Bure Interferometer, the IRAM 30 m telescope, the Australia Telescope Compact Array, and the NRAO Very Large Array. IRAM is supported by INSU/CNRS (France), MPG (Germany) and IGN (Spain). The Australia Telescope Compact Array is part of the Australia Telescope which is funded by the Commonwealth of Australia for operation as a National Facility managed by CSIRO. The National Radio Astronomy Observatory is a facility of the National Science Foundation operated under cooperative agreement by Associated Universities, Inc.

The calibrated and deconvolved data cubes and images (line and continuum) obtained with the PdBI, the ATCA, and the VLA are available in FITS format at the CDS via anonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or via http://cdsweb.u-strasbg.fr/cgi-bin/qcat?J/A+A/482/179

... components

The 1₀₁-0₀₀ multiplet consists of 9 hyperfine components with significant intensity spanning the frequency range from 9070.233 to 9073.867 MHz. Twice two components have basically the same frequency (difference of about 0.1 kHz) so that under favorable conditions there are 7 hyperfine lines observable. Full spectroscopic information for amino acetonitrile can be found in the CDMS (entry 56507).

... transitions

Note that our modeled spectrum is anyway calculated with the full LTE radiative transfer which takes into account the optical depth effects (see Sect. 3.2).
