Notes. For 3C 48, the flux density Sν as a function of frequency was taken to be log (Sν) = 1.3332 − 0.7665(log (ν)) − 0.1981(log (ν))2 + 0.0638(log (ν))3, where νGHz is the frequency expressed in GHz.

(*)

Adopted flux density, based on Perley & Butler (2013).

(a)

Secondary gain calibrator for γ Cas.

(b)

Absolute flux density and bandpass calibrator.

(c)

Secondary gain calibrator for ψ Per.

(d)

Secondary gain calibrator for η Tau.

(e)

Secondary gain calibrator for EW Lac.
