Notes. As a quality indicator for the observational conditions, we list the pwv value for the ALMA data and the rms path length error for the ATCA observations, measured at 21 GHz along a 200 m path. The latter has a decreasing influence on the data quality (i.e., phase stability) because the frequency and baseline length both decrease.
