Table 1.
Observational parameters for the ALMA data. The observations for U Ant were already presented in Kerschbaum et al. (2017).

Notes. Table columns are: beam full width at half maximum and position angle (θbeam and PAbeam), respectively, the maximum recoverable scale (MRS), the velocity resolution (Δv), and the rms noise. For each source the arrays (TP – total power; ACA – Atacama Compact Array; TM – twelve metre array) and the original project IDs that were combined are given. Parameters are given for the final, combined data cubes. ( * )The TP data for U Ant were combined with the ACA and TM arrays through feathering, leaving possible artefacts caused by resolved-out flux. Details of the data handling for U Ant are explained in Kerschbaum et al. (2017).
