CMD of the ultraviolet HST sample. The adopted magnitude limit and selection box used for the definition of the BSS population are shown. The resulting fiducial BSSs are marked with open circles. The open square corresponds to the variable BSSs identified by Drissen & Shara (1998). The box adopted for the selection of HB stars is also shown.
