NGC 5824 results for Test 1. Top left: CMD and a star-count map of the cluster. Green, red, and blue dots correspond to the MS, RGB, and BHB star candidates, respectively, and the gray circle represents the best.fit R_t parameter for this test. Note that MS candidates are omitted from the star-count map because they occupy the entire MegaCam field. Top right: Observed surface number density profile, constructed using MS, RGB, and BHB stars, along with data from Trager et al. (1995) for the cluster’s innermost region. Bottom left and bottom right: corner plots obtained for the King profile and power-law fits, respectively. The dashed black lines correspond to percentiles 0.16, 0.5, and 0.83, in that order, from left to right. R_c and R_t are expressed in arcminutes. Σ₀ is expressed in arcmin⁻². γ is dimensionless, and σ is a normalization factor of the power-law model.
