Caption: Fig. 2.

Optical photometry for NGC 1651 (left) and NGC 2173 (right), overplotted with the ﹩Z=0.008﹩ theoretical isochrones from Girardi et al. (2002); isochrone ages are listed in the figure. These plots illustrate our MSF method, where we match isochrones to the brightness of the RC and color of the unevolved main sequence to determine cluster ages.
