Example of the stellar variability search output for scan 27 from the 2015 AU Mic data. The lower panel shows the S/N vs. time for a single scan (27), with one large flare visible. The colour scale in the upper panel shows the mean-filtered data from the lower panel using a window of the width given on the y-axis to increase the S/N for flares with a duration greater than 6 seconds. The flare is mostly strongly detected for a window of 7 × 6 s, as indicated by the plus sign (+) in the upper panel.
