Abstract

We present structural parameters for 51 compact star clusters from the survey of star clusters conducted in the South-West field of the M 31 disk by Kodaira et al. (2004). Structural parameters of the clusters were derived by fitting the 2-D King and EFF (Elson, Fall and Freeman 1987) models to the V-band cluster images. Structural parameters derived for two M 31 clusters, which are in common with the study based on the HST data (Barmby et al. 2002), are consistent with earlier determination. The M 31 star cluster structural parameters in general are compatible with the corresponding Milky Way galaxy and Magellanic Clouds cluster parameters.
