StanCam quick guide

• Telescope start-up:
  Make sure that the telescope power is on, hatch(es) and mirror cover are open (see cookbook)

• Make sure that the STANCAM sequencer has been started.

• Go to the script directory (e.g. cd scripts/45-678), if needed.

• Note the Cassegrain instrument setup, especially the focus value, if you will use the Cassegrain instrument after StanCam

• Telescope setup:
  run script tcs.setup-tel-stancam on a StanCam sequencer window. This will:
  tcs.ag-off
  tcs.ccd-filter 0                 (STANCAM no filter)
  tcs.camera-probe-ccd      
  tcs.tcs-command "instrument-name STANCAM"
  tcs.tcs-command "field-rotation 0"
  tcs.offset-size 10 10
  tcs.probe-step-size 5 5
  tcs.tv-focus
  tcs.tcs-command "box-at-center"
  tcs.background-box-position 400 400
  tcs.focus-position
  
  Note, all above commands can be given from the TCS as well, e.g. focus-position

• Focus the telescope, if needed

• Preset the telescope to the target

• Choose the desired filter
   e.g. ccd-filter 4 when using the TCS
   or tcs.ccd-filter 4 when using the sequencer

• Start autoguiding, if needed, (e.g. ag-on, see the TCS pages)

• Adjust the telescope focus, if needed (e.g. tcs.focus-position 23080 or tcs.focus-delta 40

• Start integrating (e.g. expose 120) or run the script, (see the StanCam sequencer commands )

Hints & trouble shooting

• The "teloffset" x and y-coordinates are as in the "postprocessing" ds9-display.

• If the DS9/imexam etc. is in a "funny state" try the sequencer command 'killdisplay', or 'killpostprocess'
