MPE has used the PANTER facility to perform a number of recalibration
experiments of the PSPC using the engineering model.
Data have been collected to examine both the rate-gain effect
and the residual systematics in the spectral calibration, i.e., at/over:
- high count rates to examine the rate-gain effect,
- four gain states in order to investigate the amplitude and
systematics of all gain-dependent effects,
- an energy range extended from the original
pre-launch calibrations to better determine energy dependent effects.
