The Doppler shift is the effect of sound increasing or decreasing in pitch as an object moves towards or away from you. ... Light works the same way, except light is shifted to redder colours when an object is moving away, and to blue colours when an object is travelling towards us. ... Almost every object he observed had its light stretched to redder colours, indicating essentially everything in the Universe was moving away from us. ... So the Hubble constant tells us how old the Universe is. ...

... 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. ...
