Abstract
Using the UCLA infrared cameras Gemini and KCam, we have obtained J and K’ images for several globular clusters which are located in the direction of the galactic center, including Terzan 5, Terzan 9, Terzan 10, and UKS 1. Color-magnitude diagrams are constructed for giant stars in these clusters. By studying the giant branches of these clusters relative to those of standard clusters, we have derived the reddenings, metallicities, and distance moduli for the four clusters.
