Scientific paper

This catalog is the Globular Cluster Catalog published by Halton C. Arp in 1965 as part of a review paper on globular Clusters. The review focused on the slightly more than a hundred roughly spherical star clusters that have integrated color indices between B-V = 0.6 an 0.8 mag and intrinsic magnitudes between Mbol = -4 and -10 mag. They are distributed about the center of the galaxy. Such clusters contain stars that are very old and metal poor. The catalog improves upon the earlier publication by Mrs. Hogg (1959). An estimate of the completeness of the catalog is 98 percent complete for galactic latitudes above b(II)=8 degrees and 94 percent complete for low latitudes for concentration classes less than XI. This catalog lists for all 119 clusters: the NGC number, or other ID, the name, the position in equatorial and galactic coordinates, the concentration class, galactic absorption, diameter at 0.9, magnitude of 25-st brightest star, distance modulus, galactic radius, x, y, and z positions, total brightness, apparent and intrinsic colors, spectral type and radial velocity.
