I measured the LONG and PIT OLTFs and put in some simple damping loops for in both in ITMY and ETMY.  The L "plant" had very low gain compared with P, probably because of the factor of ~10 radio of the Euler matrices.  To avoid a very high gain in the filter bank, I put a gain of 10 in the L2L SensAlign and another 10 in L2L.  This gave a gain of -5 for L, with penty of gain margin.  I set the P gain to -3, again with lots of gain margin (the plot was made with a gain of -5.)
