TL;DR: In this paper, the results of an optical monitoring campaign on the active nucleus in the luminous Seyfert 1 galaxy Fairall 9 are presented, where the primary purpose of this program is to measure the response times (or lags II) of the emission lines to continuum variations and thus to extend the range in luminosity of active galactic nuclei for which such measurements have been made.
