... 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. ...

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. ...

... The two astrometry modes of the FGS are POSITION mode and TRANSFER mode. An FGS in POSITION mode acquires an object in FineLock and tracks it for an extended period of time. An FGS in TRANSFER mode acquires an object and scans the IFOV back and forth along a 45? diagonal path in detector space to sample the interference pattern fully enough to construct an S-curve. POSITION mode observing with the FGS can determine the parallax, proper motion, and/or reflex motion of a given object. ...

... The routine processing of STIS data in the calibration ``pipeline" requires an interrelated set of software tasks and databases developed and maintained by many groups at STScI. We present the systems-level design of this calibration pipeline from the perspective of the STIS instrument group at STScI. We describe the multiple interfaces to the pipeline processes that the STIS group works across in an effort to provide for the routine calibration of STIS data. ... For example, the STIS group: . ...
