Monthly Notices of the Royal Astronomical Society, 382(2): 693–6980035-8711http://hdl.handle.net/10566/762The dependence of [Fe/H] on galactocentric distance, distance from the galactic mid-plane and age is studied. Both ordinary least-squares and non-parametric regression in the form of a ‘generalized additive model’ are used. The radial metallicity slope is found to be shallower than previously claimed in the literature, and there is a significant abundance gradient perpendicular to the galactic plane. There may be a tendency for metallicity to increase with cluster age.enCopyright Oxford University Press.
