A device used with an instrument, to provide a movable reference, as the runner of a SLIDE RULE, or the rotatable bearing indicator on a radar scope. In computer systems, a highlighted point on the DISPLAY which indicates the actual working position. For graphical editing special cursors (e.g. crosses, cross-hairs) can be selected. On output the cursor is moved automatically by the computer; on input it is under user control by means of a manual controlling device. A cursor may also be a manually positionable device, sometimes magnifying lens and a reticula to be used in connection with a DIGITIZER.

In ASTRONOMY, a CORRECTION applied to the mean of a series of OBSERVATIONS on a STAR or PLANET to take account of the divergence of the apparent PATH of the STAR or PLANET from a straight line. In GEODESY, the CORRECTION applied in some geodetic work to take account of the divergence of the surface of the EARTH (SPHEROID) from a plane.
