The Hβ line shape of Akn 120
We present here the Akn 120 Hβ line profiles from 97 spectra observed from 1977 till 1990 at Crimean Astrophysical Observatory (Appendix 1). The Hβ line has been fitted with three broad and one narrow Gaussian throughout the whole considered period. The central broad components of the Hβ and a shelf...
