XMM-Newton Science Analysis System . ... The centroid will be meaningless if the region does not contain a point like source. The format and name of the quality and error data have not been agreed yet. The region selection should be carried out by first unfurling the image in a pseudo event list, then making a call to evselect (there will be an f90-callable interface), then computing the relevant statistics on the filtered pseudo event list. XMM-Newton SOC/SSC -- 2007-07-09 ...

Next: Listing Image Values Up: Image Analysis Previous: Image Analysis . Task histo is a fairly commonly used task, giving a number of image statistics and a simple histogram. Apart from the input image (keyword in ), it can take a region of interest ( region ), a range to determine the histogram over ( range ), and the number of bins in the histogram ( nbins ). ... region . ... If you do not like histo , or you would like a PGPLOT plot of the histogram, you could use the task imhist instead. ...
