Here are a bunch of plots for various events that Rachel identified as coronal dimming in her flare catalog. There are many C class events. 7 of the 30 EVE lines are shown.
The algorithm to analyze these events for slope, depth, and duration was to have the user select the end time of the event and then simply find the minimum value and associated time during that time frame. From there, depth, duration, and slope could be straightforwardly computed.
