Results of likelihood analysis.
| Photometric | Distance | g13 | g13 | |

| 47 Tuc | VI + JK | Parallax | 0.45 | 1.87 |
| NGC 362 | VI + JK | Parallax | 0 | 1.37 |
| 22 GGCs | JK | ZAHB | 0.60 | 1.48 |

Notes. The most probable values of the g13 parameter are listed in Col. 4, while the corresponding upper bounds (95% confidence) are in Col. 5. The first three rows report the results obtained for the three best studied clusters, those for which we have used both optical and near-IR catalogs, while the last two rows list the results of the cumulative analysis. Different distance scales have been used. In particular: ZAHB stays for distances based on the observed ZAHB luminosity, (2) parallax indicates distances based on Gaia DR2 parallaxes (Chen et al. 2018) and (3) kinematic indicates distances based on the best-fit of the Gaia DR2 kinematic properties (Baumgardt et al. 2019).
