Notes. Sixth and seventh columns indicate the distance within the color diagram of Fig. 7 measured in 1σ deviations form the selected objects to the limiting 1.369 M⊙ cooling tracks for relativistic and Newtonian models, respectively. Objects j and s, marked in bold, are ideal candidates with no flags to confirm relativistic models. See text for rest of columns and details.
