We present near infrared CMDs of intermediate age (>1 Gyr) populous clusters in the LMC, taken during the first science run with the Infrared Sideport Imager (ISPI) on the CTIO 4m. These observations reach a photometric depth of K ˜ 19 (S/N > 5), two magnitudes below the red clump (RC). The high precision photometry combined with the large field of view (>10 arcmin) allows us to calculate the K-band RC luminosity of both the clusters and their surrounding fields, which will be used to determine the mean distance and three dimensional geometry of the LMC.
This research was supported by NSF CAREER grant AST 00-94048.
