VizieR Online Data Catalog: ALMA obs. of 70um dark high-mass clumps (ASHES) (Sanhueza+, 2019)

For the ALMA Survey of 70μm dark High-mass clumps in Early Stages (ASHES) pilot survey, 11 infrared dark cloud (IRDC) clumps were selected from the Millimetre Astronomy Legacy Team 90GHz Survey (MALT90; Foster+ 2011, J/ApJS/197/25 and 2013PASA...30...38F ; Jackson+ 2013PASA...30...57J). MALT90 was built on the ATLASGAL 870um catalogs (Schuller+ 2009A&A...504..415S and Contreras+ 2013, J/A+A/549/A45), from which a sample of 3246 high-mass clumps was selected for follow-up in 16 spectral lines. Only 18 sources satisfy all the selection conditions, and 11 were observed in this pilot survey. The 12th target in the ASHES pilot survey is G028.273-00.167, which is in the first quadrant and was not covered in MALT90. This IRDC satisfies all requirements and has been well studied in the past by Sanhueza+ (2012, J/ApJ/756/60 ; 2013ApJ...773..123S and 2017ApJ...841...97S).

Observations of the 12 IRDCs were carried out with ALMA on different days during Cycle 3 (Project ID: 2015.1.01539.S; PI: Sanhueza) and a resubmission for Cycle 4 (Project ID: 2016.1.01246.S; PI: Sanhueza). The data sets consist of observations in band 6 (~224GHz; 1.34mm) with the main 12m array, the Atacama Compact 7m Array (ACA; Morita Array), and the total power (TP).
