[54.01] RHESSI Imaging Using the Full Energy Response

R. A. Schwartz (NASA/GSFC)

We present RHESSI image reconconstructions of solar flare hard X-ray emission obtained using the full energy response of the RHESSI x-ray detectors. To date RHESSI image reconstructions have used count rate data binned in the desired energy band and have ignored any off-band contributions or subtractions to this count rate. In many common cases such a limitation is unnecessary and the count rate can be replaced by a pseudo-photon rate where the effect of the x-ray detector response has been removed by direct and model-free deconvolution. This technique will prove particularly useful in removing the effect of fluorescent escape at low energies and allow accurate reconstruction of low energy images even at low count rates with the attenuators in place.
