Filling the Dewar

Due to safety considerations in the Hamilton Camera room, only staff members who have been trained in the proper procedures fill the dewar.

Data Directory

Data are stored in the directories /data/hamshane and /data/hamcat determined by whether the Shane or CAT telescope is being used with the Hamilton Spectrometer. If data are in the directory from a previous observer's run, please contact a Support Astronomer or Telescope Technician to clear the data directory for you. Their procedures confirm that data are archived before clearing the directory.
