We pico'd to center on the POP QPDs, which we were falling off.  POP A QPD is used during DRMI ASC, we had been using a large offset.  Now in full lock POPA is centered, and in the sdf safe and observe files I've accepted turning off the offset and setting it to 0.

We also noticed a bug with the picomotor code, which is that if someone changes the current motor while the H1:SYS-MOTION_C_PICO_A_INUSE (yellow box on medm) is showing, the current motor channel changes and the medm makes it look like the current motor has changed, but clicking will move the wrong motor.  The second screenshot shows this happening, at the time of thei first time cursor, the current motor was 6 but motor 5 was moving.
