\caption{Parameters derived from GOES data and RHESSI X-ray spectra
at the times of the April~4, 2002 drifting structure observations,
$n\rm _e^G$ is the electron plasma density derived from the GOES emission
measure and the RHESSI source volume, $n\rm _e^R 1$ is the electron
plasma density derived from the RHESSI emission measure for the
temperature 1 and the RHESSI source volume, $n\rm _e^R 2$ is the electron
plasma density derived from the RHESSI emission measure for the
temperature 2 and the RHESSI source volume, $n_{\rm e}^{\rm Rad,max}$ is the
electron plasma density derived from the radio spectrum.}
