High resolution spectroscopy of halo stars within the spectral region   3550-5000AA
  An atlas of high resolution (R=60000) in the poor studied wavelength range 3550-5000 AA for 4 metal-deficient stars in the interval of metallicity -3.0<[Fe/H]< -0.6, effective temperature 4750<Teff<5900K, surface gravity 1.6<log g<5.0 is produced. Details of the method of producing a spectral atlas, line identifications, stellar atmospheric parameters determination are described. Based on these spectral data, we determined model atmosphere parameters and calculated abundances of 25 chemical elements.
