Some RHESSI detector gains changed noticeably following the anneal. A post-anneal gain calibration was done but was not properly propagated in the Solarsoft tree as the default; this was recently discovered by Iain Hannah. Thus, spectroscopy in the front segments -- particularly 6 and 9 -- may be off by up to 1 or 2 keV if done on flares that occurred since the anneal (November 2007) and were analyzed before March 18, 2008. The new gain solution was put in its proper place in the Solarsoft tree on March 17. Spectroscopy performed before March 18 on recent flares should be redone. Further improvements to the post-anneal gain solution (running from November to the present) are intended to appear within the next three weeks, and will be announced via another email to this list. If you are not sure whether to proceed with any reanalysis now or wait for the next refinements, contact David Smith (email@example.com).
