Notes to Table 1.
| Column 1: Model number (see details below). |
| Column 2: Galaxy: LMC, SMC, or MW. |
| Column 3: Total number of stars in the selection box. |
| Column 4: Number of C stars in the selection box. |
| Columns 5 and 6: Slope and offset (at (J − Ks)0 = 1.6 mag) of a linear fit to all stars in the selection box. |
| Columns 7 and 8: Weighted mean and error in the mean for all stars and the C stars in the selection box. |
| Columns 9 and 10: Median value for all stars and the C stars in the selection box. |
| Models 1 and 2: standard model, that is, the selection box is based on 1.3 < (J − Ks)0 < 2.0 mag and −5.0 < (MJ)0 < −7.5 mag. C stars are selected as those that are C stars according to the Gaia-2M diagram AND according to the classification in the LPV2 catalogue. No background terms are included in the fitting. |
| Models 3 and 4: 1.2 < (J – Ks)0 < 2.0 mag. |
| Models 5 and 6: 1.4 < (J − Ks)0 < 2.0 mag. |
| Models 7 and 8: 1.5 < (J − Ks)0 < 2.0 mag. |
| Models 9 and 10: -5.5 < (MJ)0 < −7.0 mag. |
| Models 11 and 12: -4.5 < (MJ)0 < −8.0 mag. |
| Models 13 and 14: Fits include background terms. |
| Models 15 and 16: Fits include background terms and have −4.5 < (MJ)0 < −8.0 mag. |
| Models 17 and 18: C stars classified as such from the Gaia-2M diagram. |
| Models 19 and 20: C stars classified as such in the LPV2 catalogue. |
| Models 21 and 22: C stars selected as those that are C stars according to the Gaia-2M diagram OR according to the classification in the LPV2 catalogue. |
| Model 23: As model 3 including background terms. |
| Model 24: As model 7 including background terms. |
| Model 101: standard model but including background terms and with σDM < 0.2 mag. |
| Model 102: As model 101, with selection box 1.4 < (J− Ks)0 < 2.0 mag and − 5.1 < (MJ)0 < − 7.4 mag. |
| Model 103: As model 102, including the nearby stars with SAAO photometry transformed to the 2MASS system. |
| Model 104: As model 103, including updated parallaxes for AGB stars in OCs. |
| Model 105: As model 104, including updated parallaxes for AGB stars in WBSs. |
| Model 106: As model 105, with 1.5 < (J− Ks)0 < 2.0 mag (and −5.1 < (MJ)0 < −7.4 mag). |
| Model 107: As model 106, only retaining solutions with −4 < GoF < 10. |
| Model 108: As model 107, only retaining sources with a distance less than 1.5 times the maximum distance in the reddening map. |
| Model 109: As model 106, scaling the reddening with the distance relative to dmax. |
| Model 110: As model 108, with updated reddenings from Lallement et al. (2022) and Vergely et al. (2022). |
| Model 111: As model 110, scaling the reddening with the distance relative to dmax and with AV < 1.5 mag. |
| Model 112: as model 111, and with σDM < 0.1 mag. |
| Model 113: as model 111, with −5.2 < (MJ)0 < −6.2 mag and no background terms. |
| Model 114: as model 113, with width of the Gaussian and Lorentzian profiles fixed to a larger value (of 0.60). |
| Models 25, 26, 115. Final fits. 1.5 < (J− Ks)0 < 2.0 mag. ∆(MJ)0= 1.2 mag. No background terms. C stars selected as those that are C stars according to the Gaia-2M diagram OR according to the classification in the LPV2 catalogue For the MW it includes updated parallaxes for AGB stars in OCs and WBS and nearby stars with SAAO photometry transformed to the 2MASS system, only retaining solutions with −4 < GoF < 10, updated reddenings from Lallement et al. (2022) and Vergely et al. (2022), scaling the reddening with the distance relative to dmax and with AV < 1.5 mag, and with σDM < 0.2. |
