Spectral atlas of two peculiar supergiants: MWC314 and IRC+10420 [SSA]


An atlas of spectra of the unique high luminosity objects MWC 314 and IRC+10420 taken with the CCD echelle spectrograph (R=15000) at the prime focus of the 6-m telescope of SAO is presented. About 320 emission and absorption features of stellar, circumstellar and interstellar nature are identified in the interval between 4790 and 7520 \AA{}. Their relative intensities and radial velocities are given and the distinctions of their profiles are discussed.
