TL;DR
This paper presents a survey and analysis of 51 compact star clusters in the M31 disk's SW field, deriving their structural parameters using King and EFF models to enhance understanding of cluster properties.
Contribution
It introduces a catalog of structural parameters for 51 star clusters based on surface brightness profile fitting with King and EFF models.
Findings
Structural parameters for 51 star clusters are derived.
The catalog provides detailed measurements for future studies.
The method improves understanding of star cluster structures in M31.
Abstract
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).
