The metallicity distribution from our catalog is shown for member stars of three open clusters (NGC 2632, NGC 2516, NGC 752) and three globular clusters (NGC 3201, NGC 6397, NGC 4590). In each panel, we display the metallicity distribution of member stars both before and after applying 3 − σ clipping, depicted as step and filled histograms, respectively, with the number of remaining members annotated in the labels. Gaussian fits are overlaid as blue curves in all panels. The mean and standard deviation of [M/H] for each cluster are also presented in the respective panel. The black vertical lines indicate the metallicities of these star clusters as reported in the literature.
