RichM suggested we get the 45mHz Blends running on the Z axis for the ETMs.
After checking that our current version is in SVN, I saved a backup copy and then copied the blends from the X or Y dof with foton. Attached are Trends with the transition from Quite_90s to the 45mHz Z blends fairly obvious. Also see that there is pretty much no effect in RZ from the switch as evidenced on the optical lever. If our Z to Rz subtraction was not too good, the lower blends might reinject tilt and show up on the oplev or some other IFO signal. So far so good.
It probably should happen on the CS platforms as well.
I committed the ETM filter txt files to the SVN revision 12264.
