---------------------------------------------------------------------
03:10 : Setup done.
----------------------------------------------------------------------
03:11 : Started command file.
----------------------------------------------------------------------
03:15 : Stopped command file due to observer needed 2.6s integration(LTA1=2). web based cmd file creator tools showing that 2.6s integration possible while running the set-up. it is not possible so restarted correlator.
----------------------------------------------------------------------
03:20 : Not possible 2.6s integration(LTA1=2) for BW=100MHz
----------------------------------------------------------------------
04:30 : Restarted corr. with LTA1=4(5.3s) default mode for BW=100MHz.
----------------------------------------------------------------------
04:31 : Restarted command file.
----------------------------------------------------------------------
06:10 : Stopped command file due to wrong setup through GUI(overwrite original setup file.)(TGC)
