[Fe/H] values from the paper by Twarog et al. (1997, AJ 114, 2556) have been introduced in the database
to replace the older values from Lyngå's catalogue, for 76 open clusters. The values have been reduced
by Twarog et al. to a common scale.
Recent determinations have been tabulated for 60 open clusters, with data sources.
