Abstract:
We present a homogeneous set of stellar atmospheric parameters (Teff,
logg, [Fe/H]) for MILES, a new spectral stellar library covering the
range λλ3525-7500Å at 2.3Å (FWHM) spectral
resolution. 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.

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.
