Status of the Calibration of the EPIC-pn Camera onboard XMM-Newton

摘要

The X-ray Observatory XMM-Newton is in orbit since the 10th December 1999. In the first half year an extensive program to commission, calibrate and verify the performance of the payload has been carried out. Since then many routine calibrations, using the onboard calibration source as well as many different celestial objects, have been performed. In this paper we report on the status of the calibration of the EPIC-pn camera in general and focus on major points like the CTI evolution, the effective area, the response function and the instrumental background.
