The cartoon

Another version of the SADs cartoon but in sober black and white. This version allows for multiple nearly- simultaneous reconnection events, plus some actual numbers for the physical properties. One of them is the inferred SAD magnetic flux, which appears to be quite small. Does this mean that the SADs don't actually play a major role in flare energy release? The Asai cartoon may suggest otherwise.
