... indices[*]
We point out the work of Bica & Alloin (1986) who performed a spectroscopic study of 63 LMC, SMC, Galactic globular and compact open clusters. However, the final resolution of their spectra is too low (11 Å) to allow an analysis of standard Lick indices.

...1996)[*]
These reddening values were derived from CMD studies of individual globular cluster and are a reliable estimate of the effective reddening, in contrast to coarse survey reddening maps such as the COBE/DIRBE reddening maps by Schlegel et al. (1998). These maps tend to overestimate the reddening in high-extinction regions.

... scale[*]
Note that to derive [Z/H] from [Fe/H], the [$\alpha $/Fe] of the globular clusters needs to be accounted for.
