Table A.1.
Definition of the different groups identified in the (WRP, BP−RP − WK,J−K) vs. Ks diagram of Gaia DR2 LPVs (cf. Figs. 1 and 2), valid for the LMC.
| Group candidates | Definition for the LMC |
|---|---|
| O-rich | WRP − WK ≤ 0.7 + 0.15 * (Ks − 10.8)2 |
| – Faint AGB and RGB | O-rich and Ks ≥ 11.98 and Ks ≥ 13.5 − 5.067 * (WRP − WK − 0.1) |
| – Low-mass AGB | O-rich and Ks > 10.5 + (WRP − WK) and [Ks < 11.98 or Ks < 13.5 − 5.067 * (WRP − WK − 0.1)] |
| – Intermediate-mass AGB | O-rich and Ks > 9 + 2 * (WRP − WK) and Ks 10.5 + (WRP − WK) |
| – Massive AGB and RSG | O-rich and Ks ≤ 9 + 2 * (WRP − WK) |
| C-rich | WRP − WK > 0.7 + 0.15 * (Ks − 10.8)2 |
| – Non extreme C-star | C-rich and WRP − WK ≤ 1.7 |
| – Extreme C-star | C-rich and WRP − WK > 1.7 |
