.. _before_you_go_to_bed: Before you go to bed ==================== #. Make sure that you have completed the night report on the `HiPERCAM google site `_. #. Make sure that you have emailed all of the PIs with details of the data you obtained for them during the night. Please copy VSD into your emails. If appropriate, you should send light curve plots and ``reduce`` log files, a description of the observing conditions, and the total amount of time spent on the program. #. Make sure that you also email Antonio Cabreras (Head of Science Operations at the GTC) with a breakdown of the time spent on each program on the night. Please copy VSD into your email. #. Make sure that the comments in the ``hlogger`` observing log are up-to-date and complete for the night. #. Turn off the CCD clocks by hitting the *Power off* button on ``hdriver``. #. Shut down the observing system by clicking the *quit* button at the top-left of ``hdriver``, clicking ``File -> Exit`` at the top-left of the *ESO NGC GUI* (if open), and typing ``ctrl-c`` in the ``FileServer``, ``HServer`` and ``GTC_Offsetter`` windows. #. Archive all data obtained during the night (see :ref:`Archiving data `). #. If you used anything in the HiPERCAM crates, ensure everything is put back and the crates tidied and lids closed. #. Tidy up the HiPERCAM area in the control room. #. Put the cat out.
