Figure 34: Analysis of the internal photometric errors in CFHTLS_W_g_020241-041200_T0007 using simulations
of stars. The top panels are analyzed without clipping and the bottom panels after a 3-σ clipping. The figures show
the results for three sub-samples selected from signal-to-noise ratio (not magnitudes): S/N=10 (black), 30 (red)
and 100 (green). Each panel is split into two plots. On the left the magnitude differences between the true input
and the measured output magnitudes of simulated sources are drawn as a function of magnitude. The sub-samples
are shown in green, red and black colors. On the right, the normalized distributions for the three sub-samples are
shown. The FWHM, errors, σ=FWHM/2.35, in table 8 are derived from the histograms. Note that a magnitude
dependant offset has been corrected prior to computing the FWHM and the errors inside a magnitude bin quoted
in Table 8.
