Dear RHESSI users,

Due to the degraded condition of detector G2 (the one under the second-finest
grid), there is currently a problem with the interpretation of its
gain for all times since mid-January of 2003.  We hope to have an
improved gain solution ready within 2 to 3 weeks.

At no time should anyone be using this detector for spectroscopy alone.
For imaging and imaging spectroscopy, results for flares during
calendar year 2003 which rely heavily on this detector should probably
be held up until the new gain solutions are available.

We're sorry for the inconvenience.
