- "When sources are bight enough to look for variability at small time scales, the per-observation time binning is no longer relevant. One can easily extend the light curve estimation approach presented above to any time binning. This is demonstrated in the [following tutorial](light_curve_flare.ipynb) which shows the extraction of the lightcurve of an AGN flare."
