Notes. Col. 1 gives the colour and magnitude of the CMD. Cols. 2 and 3 list the ranges in colour and apparent magnitude, and Cols. 4 and 5 show the total number of stars in the data (Nobs) and model (Nmod) for each CMD. The stellar numbers of the three components are listed as Cols. 6 to 8 (Nthin, Nthick and Nhalo). Column 9 shows the ratio of star numbers of the model to the observations. Col. 10 lists the ⟨ χ2 ⟩ of the Hess diagrams. The last column lists the median absolute relative difference Δmed of each Hess diagram for the region redder than the turn-off.
