Notes. The reported uncertainties on SMI are formal propagated Poisson errors on star counts. We arbitrarily assigned an uncertainty of 0.1 in SMI to clusters having only red HB stars. Note that SMI values can be (roughly) converted into HBR, for comparison with other samples, by inverting Eq. (1), i.e. HBR = 2SMI − 1.0. Distance moduli, [Fe/H], and E(B − V) are taken from Paper I. Rp is obtained adopting the mean distance modulus from Paper I for all the clusters, (m − M)0 = 24.42. The three-dimensional distance from the center of the galaxy, RGC, is obtained adopting the individual distance moduli from Paper I and (m − M)0 = 24.42 for the center of M 31.
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.
