The WFS demodulation MEDM screens rarely get attention regarding their usability and accuracy, but a bit of confusion arouse during attempts to increase the input power today because of a few inaccuracies in the display of the true infrastructure. 

I've cleaned it up -- see attached. All changes were related to how the power normalization of the resulting I and Q signals is done; hopefully its a bit more clear now.

Note, though we use the exact same demodulation infrastructure for virtually all WFS, i.e. with the "WFS" library part in the 
    /opt/rtcds/userapps/release/isc/common/models/WFS.mdl
library, we've had to do special things for AS_A_RF45 signals, which now uses the "WFS_SUM" library part (in the smae library) because the SUM signal is also normalized and eventually used for LSC control, unlike any other WFS.
As such, I had to modify two screens.
The first and second attachment shows before vs. after for the standard WFS.
The third and fourth attachment shows before vs. after for the special AS_A_RF45.

Screens have been committed to the userapps repo, under 
    /opt/rtcds/userapps/release/asc/common/medm/
        ASC_WFS_SETTINGS.adl       # standard
        ASC_WFS_SUM_SETTINGS.adl   # for special AS_A_RF45

LLO should only need to "svn up" the above directory in order receive this goodness (assuming they're using the same underlying infrastructure).
