Notes.

(a)

We refer to K or Ks magnitudes for all clusters analysed adopting the 2MASS or VVV–VVVX datasets, respectively. Both K/Ks and G magnitudes listed in the table are the average magnitudes of the RC.

(b)

We adopt subscripts NIR and GEDR3 to indicate if the distance is derived from the 2MASS and/or VVV–VVVX in NIR or Gaia EDR3 (GEDR3) photometries.

(c)

The absolute magnitude in V band is calculated from the comparison with the well-known Galactic GCs following Garro et al. (2021a).

(d)

We highlight the age used in the fit of the isochrones (Fig. B.2) in square brackets.

(e)

The abbreviations indicate: GC? = globular cluster candidate; OOC = old open cluster or young globular cluster; GC=globular cluster; OC = open cluster.

(f)

We flag FSR 190, due to the high extinction which does not allow us to accurately calculate all the physical parameters especially in the optical passband.
