Bolometric PL relation. Stars in the SMC are plotted in red. The error in M_bol is smaller than the plot symbol. Some outliers are plotted with their identifier. Stars with an IR excess according to GJ17 are indicated by a green plus sign. Stars that show eclipsing or ellipsoidal variations according to OGLE are indicated by a blue cross. The classical Cepheid in the eclipsing binary OGLE-LMC-CEP-0227 (at P = 3.79 days) and the Galactic T2C κ Pav (at P = 9.08 days) are plotted as blue diamonds. The black solid line shows the relation derived from the BLH + WVIR + non-dusty RVTs with periods below 50 days in the LMC (see Table 1) plotted over the entire period range.
