Notes. Column 1: radio telescope (the array configuration is reported for the VLA and VLITE). Column 2: project code. Column 3: target name. Columns 4–5: observing frequency and bandwidth. For the VLA observations, we report the frequency and bandwidth of the two intermediate frequency channels. For the GMRT and VLITE datasets, the usable bandwidth after data flagging is reported in parentheses. Columns 6–7: observing date and time. Column 8: calibration sources used to set the flux density scale (see text for details).
