Hello Dave, Eliot, all,
it might be useful to display the attached plot showing typical flashes for C/A to centrality
of 12, 20 and 100 km.
This is a figure from an Icarus paper by Eliot Young et al. (including me) that is currently being revised.
Eliot: do you agree to release it? It gives a good feeling of what a flash is, and is worth many words.
Another point: because the flash can go above the unocculted flux, be careful not to be close to saturation. This happened in one station during the Triton occ. of Oct. 5, 2017. The surge was about 2.5 x the unocculted flux, and part of the flash is a bit saturated.
