In an attempt to look for obvious clipping in the PRC, I scanned around +/-150 urads from our PR3 alignment while in single bounce and with SR2 following along to keep AS_C centered. This was a painfully slow process as I would move PR3 until SRC2 would near its limiters, wait for it to settle down, then move again. I ended up bumped the SRC2 gains way up to help speed this up, but it only helped a bit. 

I saw no signs of clipping in the +/-150 range, so I continued in yaw until AS_C nsum finally started to decrease. This didn't happen until +500urad in Y from our starting point. We stopped here to run some more pertinent tests. I reverted all alignments back to before this test.
