The changes to the common ASC_MASTER ASC library part have been made, and committed to the svn.

Late last week, I made the changes for the 2f centering loops.  Today I added excitation points (and monitors) at the output of the ASC servos, which will make sensing matrix measuring easier.  I also added 2 more DC centering loops, which will be used to feed the Trans QPD signals to the transmons.  Finally, I created 2 filter banks CHARD_A and CHARD_B for each pitch and yaw, so that we can do some frequency dependent error signal blending.

All of these changes compile, but nothing has been installed or restarted.  We'll do that on Tues. 

Medm screens are mostly done.  I still need to increase the input and output matrix sizes, but since all the new stuff is at the end of the matrices, even if we restarted the model right now, we could use the screens as-is.  I also need to add Exc notifications to the ASC overview screen for the new sensing matrix excitations.
