Changes

** For information on the script, a logfile is produced that will be in /var/log/<TELESCOPE>DataCopyLog<MMDD>-<NUM> where <TELESCOPE> is 40in or 74in <MMDD> MonthDay <NUM> the Nth time this script has been run

Under normal operation, the system automatically updates the FITS cube header with supplementary information (filter, external trigger parameters, telescope pointing information etc.) and the moves the cube to the permanent (for the night) storage area. From time to time, it may be neccessary to do this manually, using the rescue_data tool. In particular, if the system has frozen at the end of an acquisition, but before fixing the header and moving the datra file, it will be neccessary to perform this procedure.
