Observed I,(V − I) CMD. Stars in the SMC are plotted in red and are shifted by − 0.432 mag in I to account for the difference in adopted distance (50 vs. 61 kpc). For the pWVir object OGLE-LMC-T2CEP-098 (MACHO 6.6454.5), a known eclipsing system (Alcock et al. 2002), the location of the two components is indicated by the dark blue lines. The pulsating star is the fainter, redder object (see text). Stars with an IR excess are denoted by a green plus sign. Stars that show eclipsing or ellipsoidal variations according to OGLE are denoted by a blue cross. Some stars are labelled by their identifier.
