Comparison of the 1σ area from fit on the photometry and the fit on the combined data as function of the input 
for the age-metallicity relation. At any age, the 1σ(phot) area based on the photometry is on average 13.3 times bigger than the 1σ(comb) area, based on the combined fit. The error bars are computed from the median absolute deviation.
