Difference between BB95 (gray vertical areas in panel i), BBHOP flares (green lines in panel ii), and prominent BBHOP flares (purple area along with green lines in panel ii). Panel i: merged CAZ light curve. Panel ii: BBs of the merged CAZ light curve for a zoomed-in portion of CAZJ1100+4019. The horizontal solid gray line represents S_95%, the horizontal dotted gray line represents S_75%, and the horizontal solid red line shows S_25% (with its errors shown as dotted red lines). For more plot details, see the description of Fig. 5. The BBHOP algorithm fails to find flares in low cadence periods (e.g., CRTS-epoch) due to frequent observational gaps. Notably, unlike the BBHOP algorithm, the performance of the BB95 algorithm on periods with data is not affected by the presence of neighboring observational gaps.
