A.10.1.1 Use Sky Coordinates in TOPCAT

Configuration for Use Sky Coordinates in TOPCAT action

The Use Sky Coordinates in TOPCAT action causes the sky coordinates of an activated row to be communicated to certain other TOPCAT windows that have sky position entry widgets, for instance to update the query position in the Cone Search and Simple Image Access windows, and to be used as the default position in certain queries from the Examples menu in the TAP window.

This is in most cases useful behaviour so if sky coordinates can be identified this action will be enabled by default. If you find it unhelpful however (e.g. you have typed a position into the Cone Search window position selector and you don't want it to be overwritten) it can be disabled.

Configuration:

RA Column

Dec Column

Identifies the table columns representing sky coordinates.
