Talk:RHESSI Simulations of Complicated Flares

What were you people drinking when you made the Clean image for this flare? Here's what I got with Clean and pixon using the RHESSI X-ray observations for this flare.

Of course, I did "cheat" by convolving the Clean components with a Gaussian only half as wide as the Clean-beam, and I used all nine detectors instead of 1, 3, 4, 5, and 6 that you used. I don't understand why you wouldn't use all detectors. Certainly detector #2 provides useful information on the finest structure since this image is for the 25 - 50 keV energy band. In any case, it seems to me that the Clean and pixon images agree very closely so I don't think Clean has met its match at all. In fact, I have not yet seen a flare where CLEAN and pixon images differ significantly as far as the compact sources are concerned.

Given this excellent agreement between pixon and clean X-ray images for compact sources, I am perplexed as to why you would get such a very different Clean image with your simulated data taken from the TRACE white-light image.
