S-band gain calibrators

  • Below is the current list of MeerKAT S-band gain calibrators chosen from the existing 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 in the near future.
