Plots of figure-of-merit values with respect to the number of Log-COSEBIs modes considered for two surveys with the three angular ranges  [1′,20′] ,  [1′,400′] ,  [20′,400′] . Here all the parameters except one is marginalized over. The first column correspond to MS (top plots) and MS+CMB (bottom plots) and the next two to LS and LS+CMB correspondingly. Eight redshift bins are used here. The CMB prior flattens the curves, especially in the case of MS, where WMAP7 puts tighter constrains on the parameters.
