A guide to the Astronomical X-Ray Satellite ROSAT Intended to provide ROSAT users with an overview of all technical aspects of ROSAT · With special emphasis on the calibration of the various instruments Max-Planck-Institut für extraterrestrische Physik · NASA/Goddard Space Flight Center · Harvard/Smithsonian Center for Astrophysics · University of Leicester

Descr.: This document contains the correlation between UTC and the ROSAT onboard clock for the whole mission since launch. Data are given as pairs (UTC / SCC) together with the result of a linear regression and plots of the residuals (which are typically below 10msec) · Author: P. Predehl

Analysis of the in-flight Al K_alpha data. Demonstrates the magnitude of inaccuracies recently discovered in the temporal & spatial gain correction applied by SASS, and reviews the current status of the work being done at NASA/GSFC & MPE to understand and correct for these · CAL/ROS/95-003

Details all the corrections applied to individual PSPC events during the conversion from their arrival position & pulse height channel to their corrected coordinates & pulse-invariant channel. This memo is essentially a copy of the original MPE memo TN-ROS-ME-ZA00/027, but updated and expanded to also refer to the FITS versions of the calibration files available from the CALDB · CAL/ROS/95-010

Gives a detailed description of an analytical parameterization of the PSF by Hasinger et al; as published in Legacy, 2, 77 · CAL/ROS/92-001

Addendum to the memo CAL/ROS/92-001 comparing the analytical parameterization of the PSF with a high signal-to-noise dataset by Hasinger et al; as published in Legacy, 3, 46 · CAL/ROS/92-001a

Gives a detailed description of an analytical parameterization of the PSF by Hasinger etal; as published in Legacy, 4, 40 · CAL/ROS/93-015

The gain (mean PHA channel) and quantum efficiency (count rate) of the ROSAT HRI are monitored frequently using N132D and the UV calibration lamp. The links below are to postscript files describing these quantities over the lifetime of the mission.
