\caption{\label{tbl:BT}Error analysis of the bulge fraction $B/T$ for different recovered
magnitude ranges and different bins in recovered galaxy size. The galaxy size
is represented by the half-light radius and is distributed into 4 bins
in $\log~(r_{\rm hl})$. In the top left corner bright and
small objects are found whereas faint and large objects are placed in the
bottom right corner. $\overline{\Delta B/T}$ is the average difference between introduced and
recovered values of $B/T$, while $\sigma \Delta B/T$ is the dispersion (see text for details). 
$N$ is the number of simulations used for each bin. }
