Just like ETMX earlier, restarted the HEPI guardian at ETMY to restore the same position for all dofs. No problems again. Attached is similar plot showing how different the alignment is after the restart. Again, the HEPI is exactly the same, cause we made it so. And the ISI, even though it restores no dofs, holds to its previous position to within 1 urad ( worst is RX=Pitch at ETMY,) all other dofs much less.
