Abstract: The sources were observed with the ACA in stand-alone mode in Cycle 5 in Band 6 (project codes: 2018.1.01434.S).The observations covered four spectral windows in each band. In Band 6 the windows were centred on 216.2, 218.3, 230.7 and 232.1GHz. In Band 7 they were centred on 330.75, 332.25, 343.52 and 345.6GHz. This setup covers line emission from ¹²CO(2-1), (3-2), and ¹³CO(3-2),as well as emission of other molecules. The spectral resolution of the imaged data was set to 0.75km/s in the ¹²CO and ¹³CO windows and to 1.0 and 1.5km/s in the other spectral windows in Band 6 and 7, respectively. All data were calibrated using the standard scripts and imaged using the CASA package (McMullin et al., 2007, ASP Conf. Ser., 376, 127). Self-calibration was performed using a small number of channels, typically two, across the peak of the ¹²CO line and applied to all sources in both bands. The cubes and images have improved quality compared to the data products provided in the ALMA archive. The cubes cover each spectral window imaged separately resulting in eight fits cubes per source. For each band a continuum image is generated from all the line free channels.
