Region around eclipse #8 and burst #9. a) true source light curve (red) and background (blue); b) constant cadence; c) direct subtraction; d) weighted blocks; e) weighted cells; f) weighted photons; g) iterated Bayesian Blocks with original weighting; h) iterated Bayesian Blocks with alternative weighting. The true locations of the transients are indicated by dotted vertical lines. All other methods locate the burst accurately but many fail to accurately time the eclipse ingress, which coincides with a pulse of the variable background. The weighted-photons approach performs very well in locating all transients.
