This is to announce a new RHESSI Science Nugget, “Relative and (maybe)

Absolute RHESSI Detector Efficiency: 2002-2008″, by Jim McTiernan.

The thousands of flares observed by RHESSI are used to intercalibrate its nine detectors, and we also use the standard GOES soft X-ray data as an external reference.

Please see

We publish these at roughly two-week intervals and welcome contributions.
