Unbinned light curve (Pacciani 2018) for CTA 102 obtained for E >  100 MeV (see Pacciani 2018, for a detailed explanation), and zoom-ins of the relevant periods. The horizontal segments represent statistically relevant clusters of events obtained with the iSRS procedure. They are described by duration, average photometric flux, and median time (or by starting time). Vertical lines are the error bars on the flux estimate. The set of clusters form a tree called unbinned light curve. Background is not subtracted.
