Time Lag Between the Optical Continuum and Line Variabilities of NGC 4151

Time Lag Between the Optical Continuum and Line Variabilities of NGC 4151

Using a long term spectroscopic observation of NGC 4151 (obtained with 6 m telescope of SAO Russia, between 1996 and 2006) we used Z-Transfomed Discrete Correlation Function (ZDCF) to find the time lag between the broad Hbeta and Halpha lines and the optical continuum variably.
