Comparison of mean estimates of band power between different mock setups. Plotted is the relative deviation from the Buceros case (rectangular mask, uniform depth). Blue, yellow, and red colours correspond to the Cygnus (realistic mask, uniform depth), Diomedea (like Cygnus but using individual lens sample properties for BOSS and 2dFLenS, hence only shown for GGL), and Egretta (realistic mask and depth variations) cases, respectively. Top two rows: GGL signals; bottom three: cosmic shear signals, with bin combinations indicated in the panels (those not used in the likelihood analysis are greyed out). Bands around the data points indicate the standard error determined from a jackknife estimate of variance on the ratios shown, based on mean signals calculated from 1000 realisations.
