Not illustrated. 1919 Excerpt: ... the equatorial segment1 devoid of globular clusters. If we assume that all the diminution The adopted width of the segment is 3500 parsecs; in Figs. 4 and 5 of the seventh paper the shaded area representing the mid-galactic segment is 4000 parsecs wide, but includes five clusters. For Messier 13 one-fourth of the light-path is within this region. of light through scattering (if there be any at all) occurs within this region where stellar matter appears to be greatly concentrated, the value of d is still sufficiently small to be safely ignored in all ordinary stellar problems. The magnitudes of Table III can be used for a new determination of the parallaxes of Messier 13 and N.G.C. 7006. The parallax of Messier 3, being one of the best determinations for any globular cluster, is adopted for the computation. Assuming that stars of the same absolute magnitude are involved in the final means for each cluster, we derive readily: Messier 3, T=(0000072) Messier 13, T= 0.000089 N.G.C. 7006, ir= 0.000016 The previously adopted parallaxes of the last two clusters are of0000oo and of000015, respectively. It is to be noted that the present result is based upon photo-visual magnitudes, and that the five brightest stars of each cluster have not been excluded. The almost exact agreement with the former values merely shows that the similarity in the amount and frequency of color among the giant stars in clusters makes photo-visual as well as photographic magnitude a fairly definite criterion of distance. A, 2. The diameter of Messier 3.--In the seventh paper of this series appears a discussion of the size of globular clusters. The occurrence of cluster stars far beyond the limits shown by the usual photograph has been inferred by Bailey and others from the distribution of...
