TUI supports the following offsets: . Object Arc offset by a given amount on the sky (i.e. along the arc of a great circle). ... Arc offsets are useful for moving a different portion of your object or a different nearby object onto the boresight . ... Object Arc XY this is identical to an Object offset except that it has been rotated to align along the instrument x-y axes. ... This is just like the Calibration XY offset, except that it is typically cleared when you slew to a new object. ...

... User Guide ] Key: offset A number of Miriad tasks either take or return celestial coordinates as offsets from some reference position -- invariably the observing center or the reference pixel. ... Offset celestial coordinates are always given in arcseconds on the sky. The offset, (x,y), is related to a true sky coordinate, (RA,DEC), by x = (RA - RA0) * cos(DEC0) y = DEC - DEC0 (These equations should be viewed as a definition, rather than a small angle approximation). ...
