Long-term variability of the optical spectra of NGC 4151: I. Light curves and flux correlations

A. I. Shapovalova, L. C. Popovic, S. Collin +13

Results of a long-term spectral monitoring of the active galactic nucleus of NGC 4151 are presented (11 years, from 1996 to 2006). High quality spectra (S/N>50 in the continuum nea…
