TCS SEQUENCER Command Reference


TCS commands (tcs.command in scripts)
(if used with option "-d" extended debugging information is written to the log):

  • focus-position [-d] n
    Moves the telescope main focus position to 'n'.
  • focus-delta [-d] n
    Applies a delta of 'n' to the focus position.
  • field-rotation [-d] field
    Sets the field rotation to "field"
  • rotator-auto [-d]
    Sets the rotator to automatic mode
  • rotator-manual [-d]
    Sets the rotator to manual mode
  • check-rotator-time-to-limit
    Returns the number of minutes remaining until the rotator reaches its limit.
  • rotator-turn-360 [-d]
    Turns the rotator by 360 degrees. Note that the rotator position beforehand needs to be so that a 360 turn is within the total rotator limits -201.8 to +200.5
  • set-rotator-standard
    If the resulting rotator position at a preset is about 40 degrees from the upper end stop and the rotation will be positive then a full turn of the destination position will be done to give longest possible following of the object.
    Correspondingly if the resulting rotator position is about 40 degrees from the lower end stop and the rotation will be negative then a full turn will also be done.
  • set-rotator-fast
    The rotator will go the shortest and fastest distance to the new position at a preset. This feature stays in effect until changed to 'Set-Rotator-Standard'.

  • adc-actual [-d]
    Sets the ADC prisms for the actual rotator position and zenith distance.
  • adc-mode-automatic-off [-d]
    The prisms are not moved automatically (i.e. only "manually" by explicit commands).
  • adc-mode-automatic-when-presetting [-d]
    The prisms are only moved at the start of a preset.
  • adc-mode-automatic-continous [-d]
    The prisms are constantly moved according to the actual zenith distance and rotator position. As a consequence the target will move during exposures, wrt the main guide star. This mode can only be used in combination with the FIES fiber guider. This mode can in general not be used for ALFOSC/NOTCAM .
  • adc-initialize-prism-1 [-d]
    Initializes ADC prism 1. Under normal conditions the TCS keeps the prisms initialized.
  • adc-initialize-prism-2 [-d]
    Initializes ADC prism 2. Under normal conditions the TCS keeps the prisms initialized.
  • wait-adc [-d]
    Waits for the ADC to be positioned before returning the prompt. Usefull together with telescope preset commands to only continue when the ADC is also ready. Continous ADC mode is not commissioned and not offered.
  • tel-idle [-d]
    Sets the telescope to 'idle'.
  • tcs-command [-d] "tcs-command"
    Sends the command "tcs-command" to the TCS. Example: to send the command "guide-probe-park" to the TCS, do

    tcs-command "guide-probe-park"

    or

    tcs-command "g-p-park"

    It is IMPORTANT to note that this command does not wait until this or that movement in the telescope has been done. It sends the command and returns the prompt.

    See TCS manual for details.
