Abstract

For continuum normalization we use a spectrum of a flat field. This approach allows to take into account the hardware distortions brought echelle spectrograph and to automate process of carrying out of a continuum. The given approach allows solving one of the main problems normalization on a continuum in orders which contain hydrogen lines. By development of a complex of programs of automatic processing echelle spectra, the supervision received on spectrograph have been used: GIRAFFE (SAA0); Southern Africa, SARG (TNG) Italy, BOES (BOAO) South Korea.
