摘要：

The completed High Resolution Mirror Assembly (HRMA) of the Advanced X-ray Astrophysics Facility - imaging (AXAF-I) was tested at the X-ray Calibration Facility (XRCF) at the NASA-Marshall Space Flight Center (MSFC) in 1997. The MSFC image model was developed during the development of AXAF-I (now named Chandra X-ray Observatory). The MSFC model is a detailed ray-trace model of the as-built HRMA optics and the XRCF test conditions. The image encircled-energy distributions from the model are found to generally agree well with XRCF test data and the preliminary Smithsonian Astrophysical Observatory (SAO) model. MSFC model effective-area results generally agree with those of the preliminary SAO model. Preliminary model effective-area results were reported by SAO to be similar to 5-13% above initial XRCF test results. The XRCF test conditions are removed from the MSFC ray-trace model to derive an on-orbit prediction of the HRMA image.
