Static frames showing (a) intensity, (b) RCM, (c) running difference, and (d) base difference filtering of an EIT wave in an AIA 193 Å image sequence. The RCM filter (b) uses a 56 frame window, and each image is 4 × 4 pixel spatially binned. (a), (b), and (d) are eight frame temporally binned, while (c) temporally bins the first 28 frames of the 56 frame window and subtracts them from the last 28 (binned) frames of the window. The base difference (d) uses as a base image eight frames taken at 06:51:43.84Z. Green indicates statistically significant brightenings, purple dimmings. Color bar shows approximate confidence corresponding to the colors in the filtered images.
