Subject: WFS debugging 

Trying to figure out what's wrong with the MC WFS:

1) The symptom seems to be that the control signals become very large in the pitch and then the loop breaks when they saturate. Usually this is due to a degenerate matrix or improper inversion. Most likely some of the BURT restore is bad or the analog gain for one of the WFS has been switched when Jamie was doing the "Guardian" debugging.

2) In checking this out, I found that several buttons on the WFS  screens were not working (and apparently have never been working). Please try to test things in the future...The filter bank buttons in C1IOO_MC_TRANS_QPD were using relative path names; fixed these to use abs path names. The buttons in the WFS_MASTER for the IOO_PIT banks were using IOO_PITCH instead...

2.5) Recentered beams on WFS heads with MC alignment good and MC unlocked.

3) Main problem in the WFS still not found - disabling this in the autolocker.
