The library consists of 985 stars spanning a large range in atmospheric parameters, from super-metal-rich, cool stars to hot, metal-poor stars. The spectral resolution, spectral type coverage and number of stars represent a substantial improvement over previous libraries used in population synthesis models. The atmospheric parameters that we present here are the result of a previous, extensive compilation from the literature. In order to construct a homogeneous data set of atmospheric parameters we have taken the sample of stars of Soubiran, Katz & Cayrel (1998, Cat. J/A+AS/133/221, which has very well determined fundamental parameters, as the standard reference system for our field stars, and have calibrated and bootstrapped the data from other papers against it. The atmospheric parameters for our cluster stars have also been revised and updated according to recent metallicity scales, colour-temperature relations and improved set of isochrones. File Summary:

Note (1): Spectral types are presented for stars in Alpha Per, Coma Ber, Hyades, Pleiades, M25 and NGC 6791. For the rest of the clusters, we list positions in the HR diagram, i. e., SGB = subgiant branch GB = giant branch HB = horizontal branch AGB = asymptotic giant branch Note (2): Surface gravities were derived by interpolating the location of each individual star in a VMAG-Teff diagram, using appropriate isochrones taken from Girardi et al. (2000, Cat. J/A+AS/141/371). See Section 3. Note (3): References for effective temperatures as follows: 1 = derived from B-V versus Teff relations in ALO (Alonso et al., 1996A&A...313..873A, 1999A&AS..140..261A) 2 = mean value from B-V and V-K versus Teff relations in ALO.
