FOLLOW

Causes the CCD Autoguider to follow a star image and to send error signals to the Telescope Control Computer, or to stop doing so.

Format: FOLLOW <onoroff> <n>

Examples: FOLLOW ON 1

Synonyms: FON ( FOLLOW ON 1)
FOFF ( FOLLOW OFF 1)

Comments: Valid values of the first parameter are ON and OFF; the second is the number of Autoguider integrations per guiding error is normally 1. Equivalent to n 1 GUI and GUI-OFF at the Autoguider terminal. FOLLOW does not start the telescope autoguiding, it is necessary to issue the PROBE and AUTOGUIDER commands to the TCS, either through the ICL interface or at the TCS terminal, to do this. For details of these commands refer to THE WHT USERS' MANUAL.
