XMM-Newton Science Analysis System . ... Meta Index / Home Page / Source Flagging Algorithms . Any point-source with either a raw count-rate 70 or flagged as having a mod-8 pattern is considered to have produced a read-out streak. If the raw-count rate is greater than 220 then the width of the streak is taken to be 19 pixels. otherwise 16 pixels. Flag any source whose x distance away from the streak-producing source is no greater than the streak width. XMM-Newton SOC/SSC -- 2008-10-22 ...
