Analysis and Distance Determination of the Globular Clusters in Milky Way Between -3? Z (kps) ? 3

The present paper is of three folds, first ,to provide some basic descriptive statistics parameters for the apparent and absolute magnitudes of globular clusters in Milky Way between ,where Z is the distance from the galactic plane. Second ,to establish the frequency functions and of the absolute and apparent magnitudes for these clusters .Third ,to compute the distance r of the clusters as a system assuming that ,they scatter around a mean absolute magnitude in a Gaussian distribution.The accuracy of the numerical results is very satisfactory that, the percentage errors in the mean and median magnitudes of the clusters are respectively 0.3% and 0.01%
