  We present an homogeneous set of stellar atmospheric parameters (Teff, log g,
[Fe/H]) for a sample of about 700 field and cluster stars which constitute a
new stellar library in the near-infrared developed for stellar population
synthesis in this spectral region (8350-9020 Angstrom). Having compiled the
available atmospheric data in the literature for field stars, we have found
systematic deviations between the atmospheric parameters from different
bibliographic references. The Soubiran, Katz & Cayrel (1998) sample of stars
with very well determined fundamental parameters has been taken as our standard
reference system, and other papers have been calibrated and bootstrapped
against it. The obtained transformations are provided in this paper. Once most
of the datasets were on the same system, final parameters were derived by
performing error weighted means. Atmospheric parameters for cluster stars have
also been revised and updated according to recent metallicity scales and
colour-temperature relations.
