摘要：
We present a new method for the analysis of Abell 1835 observed by XMM-Newton.The method is a combination of the Direct Demodulation technique and deprojection.We eliminate the effects of the point spread function(PSF) with the Direct Demodulation technique.We then use a traditional deprojection technique to study the properties of Abell 1835.Compared to only using a deprojection method,the central electron density derived from this method increases by 30%,while the temperature profile is similar.
