Teff and R/R from the BB fits to the UVIT photometry of the UVIT/Chandra sources (red circles with error bars). Foreground stars are omitted. The sources identified with LMXBs are marked with black squares. Sources for which the BB fits are good (χ2 < 3) are shown with additional blue markers. Evolutionary tracks for star of mass 10, 20, 30, and 50 M are shown for comparison: the evolution is generally from left to right (decreasing Teff and increasing R).
