Comparison between the wideband catalogues and the MALS DR1 catalogues of flux densities (left) and spectral indices (right) as a function of distance from the pointing centre (top) and S/N (bottom). Wideband flux densities are compared with those of SPW2, while wideband spectral indices are compared with the spectral indices obtained from fitting between SPWs 2 and 9. Where the density of points is too high (more than five per bin), data is binned with the colour of the bin reflecting the amount of data points. A binned median and standard deviation is shown by the black errorbars in all plots. In the flux density comparison plots the binned median and standard deviation using the island flux are indicated by the blue errorbars. In the spectral index comparison plots, the blue errorbars show the binned median and standard deviation of the uncorrected values of α_WB.
