VizieR Online Data Catalog: RCW120 fragmentation at 0.01pc scale (Figueira+, 2018)

Abstract : The observations of Condensation 1 were performed during Cycle 4 using 38 of the 40 12m ALMA antennas in nominal configuration C40-3 with baselines ranging from 15m to 459m. We used a continuum bandwidth of 2.227GHz in Band 3 divided into 3x117.19MHz (122kHz-0.4km/s resolution) + 1x1875MHz bandwidth. The spectral bands were centered on 93.17, 91.98, 104.02, and 102.5GHz allowing the observations of N_2H^+, CH_3CN, SO_2 transition lines and 3mm continuum emission, respectively. The primary beam at the sky representative frequency of 104.03GHz is 56''. The total observing time was 27.8-min with a system temperature between 46.7K and 69.9K and an average precipitable water vapor of 1.6mm. For this work, we used the products delivered by ALMA. The imaging was performed with the CLEAN algorithm of the Common Astronomy Software Applications (CASA) package using a Briggs weighting with a robust parameter of 0.5 and a primary beam limit of 20%. \\\\File getimages.cfg contains the configuration file used by getimages and file getsources.cfg contains the configuration file used by getsources (see Men'shchikov (2012A&A...542A..81M) for an explanation about the parameters). \\\\File catalog.dat is the getsources catalog of the sources extracted from the 3mm ALMA observation. \\\\(3 data files).
