Colour absolute magnitude diagram (CaMD) of the INT observable targets that pass the quality cuts described in Section 2.2 in grey overplotted with the RGB stars that were observed and presented in this paper in purple and green. The purple star markers correspond to the good-quality parallax used to select the RGB stars and the green triangles correspond to the bad-quality parallax used to select the RGB stars for which the distances were derived using photometry and isochrone fitting. The blue dashed lines refer to an age 13 Gyr and metallicity [M/H] −2.2 PARSEC isochrone shifted by ±0.2 mag in BP₀ – RP₀ and ±0.75 mag in M_G. The blue polygon is the absolute magnitude limited (M_G < 2.0) target selection area.
