Notes. We provide the apparent magnitude in the GRP-band and colour used in the membership analysis (see Sect. 2), the absolute magnitude in the G-band computed at the distance of the cluster (see Sect. 4.2), and the spectral type (ST). We converted the colours into spectral types (based on our observations presented in Sect. 3) from a fourth-order polynomial fit with coefficients c0 = 29.4 ± 3.8, c1 = −98.6 ± 11.4, c2 = 86.7 ± 10.7, c3 = 25.3 ± 3.5, and c4 = 19.2 ± 0.4. We explored different degrees of the polynomial to fit the data and chose the one with lowest BIC value.
