Comparison of determined H i fluxes with values obtained from HIPASS and LEDA. The left panels show the direct relation between the different catalogues, with the red line indicating the points where fluxes are equivalent. The right panels show the ratio between two catalogues as function of flux, both on a logarithmic scale, the red line indicated here the best power law fit through the data points. The first row shows the comparison between WVFS and HIPASS fluxes, while the second row shows the comparison between WVFS and LEDA. As a reference, the comparison between HIPASS and LEDA fluxes is plotted in the bottom row.
