Distribution of visual extinctions for the original sample of low ﹩T_{E}﹩ stars (solid line) and for the corresponding sample with larger photometric errors (﹩0.2< \sigma _{U}< 0.4﹩; dotted line). The cross‐hatched areas represent the stars for which the derived ﹩A_{V}=0﹩. The two histograms have been arbitrarily normalized to match at ﹩A_{V}=1﹩. The original sample is 3.4 times larger than the high ﹩\sigma _{U}﹩ sample.
