VizieR Online Data Catalog: VY CMa ALMA NaCl images (Decin+, 2016)

VY CMa was observed for ALMA Science Verification on 2013 16-19 August using 16-20 12-m antennas on baselines from 0.014-2.7km. The main objective was to map the H2O maser lines at 321 and 325GHz (Band 7) and 658GHz (Band 9), but several thermal lines identified with various rotational transitions of NaCl, TiO2, SO2, and SiO were also present in the spectral setting in addition to the continuum data. Four NaCl lines in the ground or first vibrational state are covered in the ALMA band 7 data. All of them are detected, albeit only two are unblended (see Table 1). (3 data files).
