Example of the light curve analysis, here for AIA 1600. For a given burst type (top left panel), the representation of the classification (k = 200) is plotted in a histogram (top right panel). The panels below show 15 of the 200 light curve classifications, ordered by most often to least often occurring, with the same color-coding as used throughout the paper. In this example, it is obvious that most light curves show a peak at the thirtieth frame, which is marked by a vertical dotted line and corresponds to the IB time. This indicates that IBs are statistically observed simultaneously in IRIS and AIA 1600. Similar plots (not shown) were used for the analysis of all other AIA wavelengths and burst types.
