Scientific paper

In this paper, we present the observational material of high resolution, high signal-to-noise spectra for a sample of 27 metal deficient dwarfs and subgiants. The atmospheric parameters of these program stars have been determined. Effective temperatures were derived from b -y and V - K color indices by using the calibration of Magain. Surface gravities were determined by forcing the Fell lines to indicate the same abundance as the high excitation FeI lines. Metallicities were derived from Strömgren m1 indices. These results will be used in a subsequent paper to derive heavy element abundances for these program stars.
