VizieR Online Data Catalog: CO, SO and H2CO images of AB Aur (Pacheco-Vazquez+,

The interferometric observations were carried out with the NOEMA interferometer in CD configuration between October and December, 2014 with six antennas providing the angular resolution and rms shown in Table 1. We targeted AB Aur (RA(J2000)=04:55:45.8, DE(J2000)=30:33:04.2) to simultaneously observe the H₂CO J=3_0,3->2_0,2 line at 218.222GHz, the SO J=5₆->4₅ line at 219.949GHz, the C¹⁸O J=2->1 line at 219.560GHz, and the ¹³CO J=2->1 line at 220.398GHz. The beam size was 1.6x1.5. The channels free of line emission were used to estimate the continuum flux that was subtracted from the spectral maps. To improve the signal-to-noise ratio (S/N), all maps were created with a velocity resolution of 0.25km/s.

We used 3C 84, 3C 454.3, MWC 349, J0433, and J0418 as phase and flux calibrators. The uncertainty in the calibration is about 10%. Data reduction and image synthesis were carried out using the GILDAS software.
