Aligned JAC wavefront sensors

I took an opportunity while the BSC team was in the control room and opened the light pipe and aligned the WFS on IOT1 while JAC was unlocked.

This was done at 200mW.

I used the manual adjustment knobs on the picomotor mounts as the IOT1 table is not hooked up to its pciomotor controller currently.

Got both WFS A and B as close as I could using this method. NB: pitch and yaw on QPD A are swapped as the manual pitch adjuster changes the yaw degree of freedom. I need to check this in the physical wiring for the QPDs.
