Fig. 4.
NLTE spectroscopic parameters compared with the PARSEC (solid line) and Victoria-Regina (dashed line) isochrones (Marigo et al. 2017; VandenBerg et al. 2014). The isochrones were computed using literature ages and [Fe/H] from our NLTE analysis. The colour of the points indicates their [Fe/H]. We note the different target selection for NGC 5927, where the observed stellar sample contains mostly red clump stars.
