Spatial and heliographic distributions of AR cutouts in the ARCAFF:CCD dataset. Left: heliographic map showing the locations of all extracted AR cutouts. Cutouts with longitude greater than ±65° are highlighted in red (the quantisation of the positions arises from latitude and longitude being stored as integers in the SRS reports). Centre and right: histograms of the corresponding longitude and latitude distributions, respectively. Longitudes show the expected bias against detections near the limbs, while the latitude distribution reflects the activity belts of solar cycles.
