Query: A Survey of Compact Star Clusters in the S-W Field of the M31 Disk.
  Structural Parameters. II   The King and the EFF (Elson, Fall & Freeman 1987) analytical models are
employed to determine the structural parameters of star clusters using an 1-D
surface brightness profile fitting method. The structural parameters are
derived and a catalogue is provided for 51 star cluster candidates from the
survey of compact star clusters in the South-West field of the M31 disk
performed by Kodaira et al. (2004).
