Scientific paper

Coadded high dispersion photographic spectra of Phi Herculis and o Pegasi were analysed for the purpose of testing of methods and codes we use in abundance analyses of stellar spectra. Effective temperatures and surface gravities were derived comparing the observed and computed hydrogen profiles. Elemental abundances using the SYNSPEC code were computed. Some new line-identifications are suggested and differences in abundances relative to the published values are discussed. The reliability of the SYNSPEC code in the analyses of stellar atmospheres is demonstrated.
