Notes. The flux densities of the calibrators are reported by the CASA fluxscale task, which changes reference frequency based on whether the source is a flux calibrator or gain calibrator. (a) https://skaafrica.atlassian.net/wiki/spaces/ESDKB/pages/14521467®1/L-band+gain+calibrators for properties of MeerKAT L-band calibrators. (b)Value from the old list of calibrators, no longer publicly available.
