Erratum: ``Massive Perturber-driven Interactions between Stars and a Massive Black Hole'' (ApJ, 656, 709 [2007])
Abstract
There is an error in the plotted cumulative mass function of the giant molecular clouds in Figure 2 (top panel, two rightmost curves). Due to a misinterpretation of the mass estimates in Table 1 of T. Oka et al. (ApJ, 656, 709 [2007]), Figure 2 includes 12 (out of 60) data points that are multiple entries for the same clouds, expressing alternative mass estimation assumptions (we thank R. O'Leary for pointing this out and T. Oka for clarifying the issue). The corrected observed ratio of second moments of the mass function μ2 in Table 2 should be modified downward to 108 for model GMC1 and to 106 for model GMC2. However, the analytic power-law fit for the mass function that was actually used in the numerical calculations was very conservative to begin with, and still conservatively underestimates μ2 by a factor of 2. Therefore, the results presented in the paper remain unchanged.
