VizieR Online Data Catalog: DSHARP I. Sample, ALMA obs. log and overview (Andrews+, 2018)

The Disk Substructures at High Angular Resolution Project (DSHARP) ALMA observations were conducted in 2017 May-November as part of program 2016.1.00484.L. All measurements used the Band 6 receivers and correlated data from four spectral windows (SPWs) in the dual polarization mode. The continuum was sampled in three SPWs, centered at 232.6, 245.0, and 246.9GHz, each with 128 channels spanning 1.875GHz (31.25MHz per channel). The remaining SPW was centered at the ¹²CO J=2-1 rest frequency (230.538GHz) and covered a bandwidth of 938MHz in 3840 channels (488kHz channel spacing, 0.64km/s velocity resolution).

The plan was to observe each target briefly in the C40-5 (hereafter "compact") configuration, and also for ~1hr in the C40-8 or C40-9 (hereafter "extended") configurations. The compact observations are necessary to recover emission on the larger angular scales that are not sampled in the extended configurations. The actual observing log is provided in Table 2.

We relied on archival ALMA observations of five targets (IMLup, HD142666, Elias24, Elias27, and HD163296) instead of obtaining new compact data, and folded in archival data for three other targets (HD143006, AS 205,and AS209). Information about these data sets are compiled in Table 3.
