Comparison of flux densities between the MALS wideband catalogue and the SPW catalogues from MALS DR1, as a function of S/N. The median flux density ratio is indicated with the black errorbars. The blue errorbars indicate the median flux density ratio using Isl_Total_flux from the wideband catalogue. In nearly all cases the median flux density ratio is around 1.03, but is higher for SPWs 5,6, and 7, which are badly affected by RFI and have significant amounts of data flagged.
