The bias slider values that were stored in the SDF SAFE file were old.  When there was a boot fest last Thur of ETMY SUS (alog 40913), these values got restored and the ETMY no longer pointed to ~0 on the Oplev.  Today I trended those values an dataviewer in order to restore them.  The latest values which we mechanically pointed the ETMY to, used a little bit of bias:

PIT  34.4

YAW -105.0

However these values don't put it on the Oplev in PIT now.  Today it wants bias slider values below in order to be well centered on the OL:

PIT  -135.6

YAW  -105.0

Whatever.  So many mysteries, so little time.  Door closed.

I have loaded these newest bias values into the ETMY SUS SDF SAFE file.
