To protect the OMCR QPD  sled from pulse damage in case of the lock loss without working fast shutter (that is, once we're in full lock, see E1400405), OMC refl beam was misaligned from the sled in PIT.

5th pico mount for HAM6/ISCT5, which corresponds to one of the two pico mounts in front of the OMCR QPD sled, was moved in PIT by four magnum steps (+40000 counts).

Before: (X,Y)=(7900, -3402)

After: (X,Y)=(7900, 36598)

Before the move, the beam was more or less centered on the QPDs.

Note that the picomotor names for HAM6/ICST6 are messed up, and you cannot tell what is what from the MEDM screen nor H1:SYS-MOTION_C_PICO_C_CURRENT_NAME, according to Dan.

Pico 1 = AS A centering

Pico 2 = AS B centering

Pico 3 = AS C centering

Pico 4 = nothing

Pico 5 = Upstream(?) OMCR QPD sled pico

Pico 6 = Downstream(?) OMCR QPD sled pico
