1 Averaged values of MV, (B-V)0 (Cols. 3, 8), (V-I)0 (Col. 5), and difference in colour index between emission and non-emission line stars (Cols. 4 and 9 for (B-V)0 and Col. 6 for (V-I)0. Columns 8 and 9 provide data from McSwain & Gies (2005) stars in the Galaxy (``Galaxy''). Crude error estimates (1$\sigma$) are 0.054 mag for the SMC (B-V)0 values, and 0.030 mag for the Galactic (B-V)0 values.
