/* Troubleshooting & avoiding trouble */
* If QUARTZ crashes, and complains of a Merlin/transputer error, you will need to go to the Coude room, duck under the coolant pipe, locate the blue Merlin transputer on the shelf below the optical bench and press the ~central red button. Then restart QUARTZ.
* If the orders do not match the requested prism position, initialise the prism with "Find ref" and move to the requested prism position again. You may have to repeat this a couple of times for the prism/camera to reach the requested position.
== '''Instrument shutdown''' ==
* Ensure that the APD and all lamps are switched off.
* Ensure that the fibre flat filter (silver knob on telescope) is out of beam, or you may forget it the following night.
* Leave the QUARTZ software running (the technicians need to check the temperature of the detector during the day).
* Stop the APD count plotting software and shutdown the windows laptop.
* If you haven't filled the cryostat since midnight, please do so.
* Shutdown the telescope using the printed recipe, stuck to the shelf above the TCS.
