Comparison of the distribution of ﹩A_{V}﹩ values derived for the hot (﹩T_{E}> 12,000﹩ K; thick solid line) and cool (﹩5500< T_{E}< 6500﹩ K; thin solid line) stars. The dashed areas at ﹩A_{V}< 0﹩ indicate the number of stars with ﹩A_{V}=0﹩, where we have set the height of the bin equal to the number of stars with ﹩A_{V}=0.01﹩ and the area to represent the number of stars correctly. The two histograms have been arbitrarily normalized.
