Full disk AIA and CWT images illustrating the detection of BPs. Panel a: full disk AIA 193 Å on 01 January 2020 at 01:00:05 UT. Panel b: 2D CWT at the active region scale, a_AR. The active region is detected by applying a threshold value at the 97th percentile of the CWT value. This threshold area is the area within the red contour. Panel c: 2D CWT at the BP scale, a_BP. The active region is masked by removing the area denoted by the red contour, as in panel b. The larger black circle is applied at 0.7 R_⊙, obscuring limb, off-limb, and edge effects. In this case, the active region mask is outside the limb mask. Panel d: full disk AIA 193 Å on 01 January 2020 at 01:00:05 UT. Candidate BPs are shown as white crosses. Masked areas are denoted by red and black contours.
