Analysis

At their most basic, these clusters have the same relative shape as globular clusters, though they are visibly more extended. The control cluster in M31 will be used as a visual reference as to how the clusters should appear. This was the first criterium for catagorization of the clusters. Next, the diameter of the cluster was measured, as these clusters should have a larger diameter than globular clusters. Finally, V-I photometry was analyzed, as these clusters should have high V-I values, however, this would not differentiate them from globular clusters. A galactic average for M33 was compiled by averaging the V-I values of 102 known globulars in M33, which was .713. The average of my candidates was .822. As three dimensional profiles were analyzed, they all mached profiles of globulars in both M31 and M33. They displayed a singular raised promentory in the center of the profile. This would indicate that the clusters were not extended, but rather were globulars. V-I values were consistant with those of globulars in M33, indicating further that the clusters were not extended but rather globular.
