Comparison of GSP-Phot distances in star clusters against literature values. For 2019 star clusters (nearly 200 000 stars) spanning distances up to 13 kpc, we indicate on the y-axis the median offset (dot), and the 50% quantile (line) of all member star distances with respect to cluster distances taken from Cantat-Gaudin et al. (2020). Above ∼2.5 kpc (∼15% of the cluster members), GSP-Phot systematically underestimates distances (see the discussion Sect. 3.1).
