Commands

resumeGuiding

Description: Resume current guider operation. This command will restart a guider operation with the last values used in startGuiding. If no previous startGuiding command was issued, since the last time the CSC was enabled, the command will be rejected.

EFDB_Topic:

Guider_command_resumeGuiding

startGuiding

Description: Start guiding using the input information. The command returns as soon as guiding starts, before the first interation is completed. If it fails to find a guide star in the provided guider region, the CSC will go to fault state.
