Abstract:
We present age measurements for 195 star clusters in the Small
Magellanic Cloud based on comparison of integrated colors measured
from the Magellanic Clouds Photometric Survey with models of simple
stellar populations.
Description:
Our cluster images are drawn from drift-scan imaging of the central
4.5°x4° of the SMC in U, B, V, and I done with the Las
Campanas Swope Telescope (1m) and the Great Circle Camera between 1996
November and 1999 December.
