[BLAST_SHIFTS] ABS target sequence

Hello,
    I have set up the ABS with one more mode, 'd_ten+.cycle',
that sets the |3> and |6> tensor+ target state. The scripts
'd_ten+.cycle' and 'd_ten-.cycle' set the target states until
you execute a new command/script to change the target state
or turn it off with 'd_off.cycle'. The scripts live in the
'~blast/pro2003/ABS' directory.

I have also finished the sequences that measure the settings
of the rf-transitions as a function of static field in the
mft and sft magnets. The scripts live in ~abs/ABSsoft/SCANS
and are called 'scan_sft.sh' and 'scan_mft.sh'. To run the
scripts you first exit any other target sequence, go to the
above directory, and execute the scripts (no '&'). They scan
the static fields with predefined values for gradient field
etc. for the MFT14, MFT34, SFT26, and SFT35 transitions. At
the end of the measurements the time stamp of the start of
the measurements is attached to the data files and they are
moved to the ~abs/ABSsoft/SCANS/DATA directory. A root session
automatically opens up and displays the data on screen and
produces ps-files of the root display in ~abs/ABSsoft/SCANS/PLOTS
with the same time stamp as the data files attached to it. The
root session can then be closed to continue the next measurement.
Copies of the scripts and important init files (more detail about
these in the manual) are copied to the ~abs/ABSsoft/SCAN/LOGS
directory with the same time stamp. The time stamp of the latest
scan can be found in the file 'scan_time.log' and the history
of previous scans can be found in 'scan_hist.log'. The scans
take about 1 hour to finish if you do both sft and mft scans.
