#### A.10.1.2 Send Sky Coordinates

Configuration for Send Sky Coordinates action

The Send Sky Coordinates action causes the sky coordinates associated with the activated row to be sent using SAMP to one or all suitable applications. It sends a message with the MType `coord.pointAt.sky`, so at least one external SAMP client subscribed to such messages must be registered.

One way to use this action is to configure it to transmit to a viewer of all-sky imagery such as Aladin. Then whenever a row is activated, Aladin will change its view to show imagery at the sky coordinates corresponding to that row.

Configuration:

RA Column
Dec Column
  Identifies the table columns representing sky coordinates.
Target Application
  Determines which external client(s) to send the messages to. The default is "All Clients" which will send it to all eligible applications, but you can select just one. Clicking the selector also serves to indicate which clients capable of acting on this message type are currently registered. If there are none, the action will be disabled.
