AbstractAn atlas of high resolution (R = 60 000) CCD-spectra in the wavelength range 3500–5000 A is presented for four objects in metallicity range -3.0 < Fe/H < -0.6, temperature range 4750 < T_(eff) < 5900 K, and surface gravity range 1.6 < lg g < 5.0. We describe the calibration of the stellar atmospheric parameters using Alonso's formula based on the method of infrared flux and outline the determination of the abundances of a total number of 25 chemical elements. An analysis of the abundance determination errors for different chemical elements is carried out, and a method is provided for the observations and reduction of spectral material. Properties of the method of producing an atlas of spectra and line identifications are described.
