Caption: Figure 3.

Color–magnitude diagrams in two of the PHAT survey filters for solar-metallicity clusters at four fiducial ages. Horizontal lines indicate three possible values for M _lim: −2.0, −3.0, and −4.0. Stars fainter than these lines are considered part of the unresolved component. The black clusters have no extinction, while the red clusters have A _V = 2.0 mag.
