Abstract
ALMA early science cycle 3 observations were conducted in a compact configuration on April 23rd 2016 with 13.1 minutes of total time on-source and in an extended configuration on September 8th 2016 with 26.2 minutes of total time on-source. The array configuration provided baselines ranging between respectively 15 and 463 meters, and between 15 and 2483 meters. During the observations the precipitable water vapor had a median value at zenith of respectively 1.64 and 0.56mm.
Two of the four spectral windows of the ALMA correlator were configured in time division mode (TDM) to maximize the sensitivity for continuum observations (128 channels over 1.875GHz usable bandwidth). These two TDM spectral windows were centered at 234.16GHz and 216.98GHz. The other two spectral windows were configured in frequency division mode (FDM) to target the 12CO J=2-1, 13CO J=2-1 and C18O J=2-1 lines with a spectral resolution of 61kHz, 122kHz, and 122kHz respectively.
