Comparison between outlier detections, using the three-sigma threshold (blue-shaded region) around the mean (horizontal solid black line) and IF with a contamination parameter of 0.1. The colored points are outlier candidates detected by IF, and the red points are true positive enhancements filtered by detecting corresponding FUV continuum emission. Top: 2014-10-22 M-class flare with the IF accurately detecting the rising and decay phase of the enhancement. Bottom: 2014-03-29 X-class flare, with the IF detecting enhancements in cases where a simple intensity threshold would fail. The dotted blue curve represents the GOES flux. The dotted magenta curve represents the time derivative of the 3 s averaged GOES flux (arbitrarily scaled), often used as a proxy signature of nonthermal processes.
