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.py tool. In particular, if the system has frozen at the end of an acquisition, but before fixing the header and moving the data file, it will be neccessary to perform this procedure.
* Open a terminal. Find your data in the spool directory. It's stored in a directory named /data/spool/<CCYYMMDD><index>.<HHMMSS> (where index is the index, CCYYMMDD is the date and HHMMSS is the time the acquisition started). For example, /data/spool/201503250002.141026/ . Go Use ssh to this directoryconnect to the SHOC host computer:
ssh shoc74in@shoc74in.suth.saao.ac.za
or
ssh shoc40in@shoc74in.suth.saao.ac.za
When prompted for the password, use the password for the 74in or 40in user.ssh shoc74in@shoc74in.suth.saao.ac.zaThen go to the directory containing the spooled files:
cd /data/spool
ls -l
