Commands and functions of the telescope control system.

pigoffTurn off guiding, release motor
pigxr?Query for actual x position [1/10 arcsec]
pigyr?Query for actual y position [1/10 arcsec]
pigx=%dSelect x position (set point) [1/10 arcsec]
pigy=%dSelect y position (set point) [1/10 arcsec]
pigactuLet actual position be set position
pigenc=%dSet guiding mode (0 = sensor, 1 = encoder guiding)
pigenc?Query for guiding mode (0 = sensor, 1 = encoder guiding)
pigxs?Query for selected x position
pigys?Query for selected y position
piggoGuide to selected position
piggfGuide to selected position and follow solar rotation
pigrunxyGo to selected position but do not guide
pigabortAbort going to selected position (Stop guiding mode)
pigmco=$m$nnManual control commands [m = speed, nn = direction]

piggmode?Query for motor status (possible answer 0–6)
0 = motor is free
1 = manual control active
2 = guiding without following solar rotation
3 = guiding and following solar rotation
4 = flatfield mode active
5 = go to sun active
6 = go to home position active

pigi?Query for intensity
pigthimin=%dSet threshold for minimum intensity
pigimin?Query for minimum intensity
pigthdelta=%dSet threshold for guiding accuracy [1/10 arcsec]
pigthdelta?Query for threshold of guiding accuracy [1/10 arcsec]
pigloops=%dSet number of averagings for position sensor (default is 500)
pigloops?Query for number of averagings of position sensor
pigffmx=%dX-length of flatfield area [1/10 arcsec]
pigffmy=%dY-length of flatfield area [1/10 arcsec]
pigffms=%dFlatfield motor speed (1 = slow, 2 = medium)
pigffm?Query for all flatfield parameters (e.g., 3000,4000,2)
pigstartffmStart flat field mode
piggosunTelescope go to sun
piggohomeTelescope go to home position
pigsb?Query for status
