GCLF of DF44. Left: raw GC candidate counts, estimated background counts, and completeness curve derived from artificial star tests. Right: background-subtracted and completeness-corrected GCLF. Light gray bars show the background-corrected counts, while the dark gray component indicates the additional correction applied for incompleteness. The red curve shows the Gaussian GCLF obtained from the unbinned fit, with a turnover magnitude of MV,TO = −7.12 ± 0.22 mag and a dispersion of σ = 0.89 ± 0.13 mag. The two brightest bins, which contain likely outliers, are excluded from the fit. Summing the corrected bins gives a total population of NGC = 73.1 ± 8.6.
