S-band gain calibrators
Below is the list of MeerKAT S-band gain calibrators chosen from the MeerKAT L-band list.
Some sources have been excluded due to extended structure.
Sources were observed at the S4 sub-band (2625 MHz to 3500 MHz). Each source was observed over several 7.5-minute scans scattered over a period of a few hours.
The list below is subject to change as we will add more calibrators as the S-band is being commissioned.
