TL;DR: In this paper, the authors present ground-based optical photometric monitoring data for NGC 5548, part of an extended multi-wavelength reverberation mapping campaign, and confirm significant time delays between the continuum bands as a function of wavelength, extending the wavelength coverage from 1158 to the $z$ band.
