A grid of synthetic spectral energy distributions, representative of old stellar populations, has been used to derive colors in different photometric systems, and to compare the theoretical predictions with observational data for galactic globular clusters.

AbstractWe present a multiwavelength photometric analysis of the innermost (3×3 kpc2) Globular Clusters (GCs) of M87. Their Spectral Energy Distributions (SEDs) were built with J and Ks imaging obtained with NaCo at the VLT, along with HST UV-optical archival data. Using both Galatic GC templates and stellar population models, we derived ages (> 10 Gyr) and metallicities ([Fe/H]~ −0.7) for these clusters (e.g: Cohen et al. 1998). These GCs have lower metallicities than its host galaxy. This agrees with the idea that the GC population formed earlier than the bulk of the stars.
