Something is wrong with ETMY stage 2 RX Tbetter....  we clearly have less opLev peak to peak when we turn this to Tcrappy. 

So the configuration we are using now is Tbetter everywhere except Tcrappy on RZ on stage 1 +stage2, and Tcrappy on stage 2 RX, sesnsor correction from the ground to stage 1 in X Y and Z. 

We also briefly tried T750 on stage 1 Z motivated by llo alog 12164, this wasn't good so we will have to do a more thoughfull job of importing those improvements.
