  • We present a new technique for choosing spatial regions for X-ray spectroscopy, called “contour binning”. The method chooses regions by following contours on a smoothed image of the object. In addition we re-explore a simple method for adaptively smoothing X-ray images according to the local count rate, we term “accumulative smoothing”, which is a generalisation of the method used by FADAPT. The algorithms are tested by applying them to a simulated cluster data set. We illustrate the techniques… CONTINUE READING
