Further determination of interband lags between variations in B, V, R, and I bands in active galactic nuclei

摘要

New estimates of the interband lags between variations in the B band and variations in the V, R, and I bands for three active galactic nuclei (AGNs) are present. In contrast to the previous study by Sergeev et al. (2005), the effect of the contribution of the broad lines to the bands is taken into account.
