FLARE 4, 21-APR-2002:

Flare4LCLightcurve for flare 4

Flare4FootpointsEarly image of the "footpoints". Contains thermal contamination.
This is the next image of flare 4 - the footpoints are really clean and easy to discern here, as I imaged in the 35-100 keV range. I'm just going to make one more image now of this with a 6-12 keV interval contoured on top so that we can have a really clear idea of where the thermal part of the flare is located relative to the nonthermal.

Ok, here I've contoured a 6-12 keV image over a 35-100 keV one. Both are from the same interval -- 01:12:00 to 01:14:00 -- near the beginning of the flare (right after the last attenuator interruption). This should be giving us a pretty clear depiction of the structure of the flare - in terms of general footpoint and top location.

This is just a redone version of the image at the top of today. There were too many contours to include all of the later intervals, but I wanted to redo the earlier, shorter ones and change them from 15 seconds to 12 seconds, as we get more reliable images if we use intervals that are divisible by 4 seconds.
