\subsection{HST Data and Photometry}
Photometric data were obtained using the PYRAF task {\bf phot} and were converted to absolute magnitudes by subtracting the distance modulus of the galaxy from the magnitude of the cluster. The magnitudes of each cluster and each model point were then converted to ``colors'' by subtracting magnitudes at different filters from one another. Since this process depended on which filters the galaxy had images in, but the result was always three to four linearly independent colors depending on the number of usable images; in the case of ngc-3032: NUV-V, F475W-V, and V-I were the three colors used.
