Mass functions predicted by the MMK model in our four annuli. The MF in annulus 4 (A4) reproduces the input global MF, except for the very highest masses, which were not observed here and are predicted to be somewhat segregated toward the cluster center. The calculated MFs in the inner annuli are not power laws, but nevertheless are crudely consistent with the power‐law slopes derived in § 5 of the text. A comparison of the model predictions to the observed LFs is provided in Fig. 12.
