Generate tracking plots (.pdf) at the end of a scan

Program is started at boot time and generates tracking plots at the end of scans. The program runs permanently and is monitored by BigBrother. It uses /ncsServer/mrt/ncs/var/work/plotTracking as working directory to write the .pdf plot files.

Link 30mTrackingLast-1.pdf is a hardlink to the last plot.


Monitoring is done on the monitoring VNC mrt-lx1:26. It uses gv to show the plots.
