Which detectors can I use to analyze this flare?

From RHESSI Wiki

This is the most common question we get asked by many people trying to analayze RHESSI imaging and/or spectroscopy data. The answer is not always easy and it is becoming more and more difficult as the individual detectors respond differently to radiation damage and to the four anneals that have now been completed.
