The target region G351.77-0.54 was observed with ALMA in cycle 2 in the 690GHz band with 42 antennas in the array. One noisy antenna and very short baselines have been flagged because of outlying amplitudes. This results in a baseline length coverage from 40m to almost ~1.6km. The total duration of that one execution of one scheduling block was 1h40min with an on-target time of 35min. Because of the large number of antennas, even in such a short time, ALMA achieves an excellent uv-plane coverage.This results in an almost circular beam and allows us to recover spatial scales between approximately 0.06" and 2.7". The phase center of the observations was RA (J2000.0) 17:26:42.568 and Dec (J2000.0) -36:09:17.6. (2 data files).
