Power-law relationships used to calculate primary calibration flux densities for AMI for two calibrators, 3C 286 and 3C 147, are shown with ± 5% uncertainty limits as the grey filled bands. The AMI frequency band is shown in black. Flux densities for both sources at 30 and 44 GHz taken from the Planck Compact Source Catalogue (Planck Collaboration XXVIII 2014) are shown as points with errorbars.
