These plots show amplitude vs frequency for the non-AMPLITUDE calibrators in each measurement set, comparing the pipeline-derived flux density Sderived to the catalogue flux densityScatalogue reported by analysisUtils, online source catalogues, and/or recorded in the ASDM. In these plots, Scatalogue is extrapolated using the spectral index to cover the frequency range of the spectral windows.
QA metrics are calculated by comparing the flux density ratio Kspw=Sderived/Scatalogue for each spectral window to the ratio for the highest SNR spectral window. This metric evaluates how consistent the relative flux calibration is from spectral window to spectral window for each calibrator; it does not evaluate whether the absolute flux calibration is reasonable as compared to the catalogue measurements. All QA scores based on this metric are included in the Pipeline QA section at the bottom of this page.
