Measured positions and B and V magnitudes of 910 stars to a limiting V magnitude of 15.6 in the central 2.5 arcmin of the globular cluster M13 are examined. Integrated magnitudes are computed by summing the luminosities of individual stars brighter than a V magnitude of 15.7 and lying within a circle of unspecified radius. The results are compared with integrated magnitudes measured photoelectrically to distances of 0.245 to 0.905 arcmin from the cluster center. It is shown that the integrated photoelectric observations cover all stars roughly up to the main-sequence turnoff point. The distributions of giants and horizontal-branch stars as a function of distance from the cluster center are found to be identical out to a distance of 8 arcmin.
