 | | Analytical representations for the point spread functions, p, for the ROSAT imagers XRT-PSPC, XRT-HRI, and XUV-WFC are found by detailed estimations both, from in-flight data as well as from pre-launch calibration data. |
 | | For the PSPC, the PSF model adopted, its physical justification and the data sets used in the PSF estimation, ground calibration data and in-flight data, are described in a series of three articles [Hasinger et al.1992], [Hasinger et al.1993], and [Hasinger et al.1994]. |
 | | In the case of the WFC, the point spread function will be defined differently; the one-parameter family of circles will be replaced by a certain one-parameter family of ellipses. |
