Notes. The first column gives the GC identification, as in the Bologna catalogue (Galleti et al. 2004). Second and third columns give the coordinates of the objects, in J2000. Fourth column shows the projected distance of the cluster to the centre of M 31 (see text in Sect. 2.1). Fifth column shows the S/N of the spectra as given in the corresponding paper; when this information was not available (clusters B302, B305, B307, B316, B331, B354), we estimated the S/N around 5000 Å using standard IRAF2 routines. Sixth column gives the reference of the spectra: (a) for Beasley et al. (2004) and (b) for Alves-Brito et al. (2009).
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
