[G14_run] linear polarization

[Ken Livingston]

Hi All,
I had a look at the lin pol for Sunday's test runs.

Here's the peak for 1.4 coh edge / 4.4GeV beam.

The labelling in wrong, PERP is RED, PARA is BLUE.
Looks good. Probably >85% at the peak. PERP better than PARA as we saw 
online.
I'll try and get these fitted over the weekend and do the rest of the 
peak positions we tried.

Good luck with the target.

Cheers,
Ken
