摘要
利用对象重建的直接解调方法，我们对EXOSAT卫星ME探测器银道扫描观测数据进行了重新分析，研究了在以往的分析中难以分辨的几个天区中的分立X射线源．利用Bootstrap方法，我们对成像结果进行了统计误差分析，给出了点源位置和流强的误差．
We have reanalyzed the ME /EXOSAT galactic plane scan observational data with direct demodulation technique. Especially, in this paper, we have studied the discrete X-ray sources in the regions which were unresolved in previous analyses.Using the bootstrap method, we have analyzed the statistical accuracy of the results and determined the position and flux errors of these sources.
