LSST AGN SC Cadence Note: Two metrics on AGN variability observable
  We have developed two metrics related to AGN variability observables
(time-lags, periodicity, and Structure Function (SF)) to evaluate LSST OpSim
FBS 1.5, 1.6, 1.7 performance in AGN time-domain analysis. For this purpose, we
generate an ensemble of AGN light curves based on AGN empirical relations and
LSST OpSim cadences. Although our metrics show that denser LSST cadences
produce more reliable time-lag, periodicity, and SF measurements, the
discrepancies in the performance between different LSST OpSim cadences are not
drastic based on Kullback-Leibler divergence. This is complementary to Yu and
Richards results on DCR and SF metrics, extending them to include the point of
view of AGN variability.
