Classes of visually inspected variable detections. A quarter of n_var = 2654 was inspected and classes are presented as colored disks for each pixel. The most populated class at each pixel is shown. Flares are in dark blue, bumps in light blue, multiple flares in dark orange, multiple bumps in light orange, eclipses and dips in purple, linear in green, and random in gray. The size (area) of the disk corresponds to the number of detections belonging tothe most populated class in a given BMU pixel.
