Beginning of ReadMe : J/A+A/278/36 M 31 new OB associations (Magnier+ 1993) ================================================================================ Automated identification of OB associations in M 31 Magnier E.A., Battinelli P., Lewin W.H.G., Haiman Z., Van Paradijs J., Hasinger G., Pietsch W., Supper R., Trumper J. <Astron. Astrophys. 278, 36 (1993)> =1993A&A...278...36M (SIMBAD/NED BibCode) ================================================================================ ADC_Keywords: Associations, stellar ; Positional data Keywords: galaxies: individual: M 31 - galaxies: spiral - galaxies: star clusters - methods: data analysis Abstract: A new identification of OB associations in M 31 has been performed using the Path Linkage Criterion technique of Battinelli (1991A&A...244...69B). We found 174 associations with a very small contamination (<5%) by random clumps stars. The expected total number and average size of OB associations in the region of M 31 covered by our data set (Magnier et al., 1992, Cat. II/208) are 280 and 90pc, respectively. M 31 associations therefore have sizes similar to those of OB associations observed in nearby galaxies, so that we can consider them to be classical OB associations. This list of OB associations will be used for the study of the spatial distribution of OB associations and their correlation with other objects. Taking into account the fact that we do not cover the entire disk of M 31, we extrapolate a total number of associations in M 31 of 420.
