... This makes spatial event selection very hard of even impossible in cases where the object is too faint to clearly stand out against the X-ray background. movecalc takes an event table with aspect corrected X / Y coordinate columns (as generated by task attcalc ) and adds two new columns X_MOV / Y_MOV (different names can be specified via parameters xmovcol / ymovcol ) containing the corresponding coordinates in a reference frame that is centered on the moving object at all times. ...
