To save the data in a disk file: push on "Save". The software
builds automatically a name of the type: "scan_nnn.data",
where nnn is the scan run number, incremented automatically. The current run
number is stored on disk, so unless a disk crashes, you can reboot the VME or
delete a data file without resetting this number. Read the run number on the
MEDM screen and record the file name in the e-logbook. The file will be stored
in 
gougnaud/arc2/ARC. As the file is big (2*7000 channel histogram
per scanner), purge or compress your own data files. gougnaud belongs
both to hac and the CUE, thanks to Javier. So you do not need "ftp"
to copy it inside the CUE; the cp command works as far as you have the good
file access. Write in the e-logbook the final path of the file in the CUE.
Example of scan file: scan_159.data
