Edit, JCD: What this really means is that our DC MC pointing is bad, and we need to move the MC suspensions to offload the WFS. (All of the WFS output numbers for MC1 and 3 were around 100, which is pretty big for those numbers). We should resurrect the WFS offloading scripts so that we can do this more regularly, and not have to do it by hand.

Aligned MC to offload the WFS
1. Turned OFF the WFS feedback servo.
2. Aligned the MC suspensions by moving the pit and yaw sliders. MC trans sum brought from ~11000 counts to ~15000 counts. MC RFPD DCMON reads 0.45 counts.
3. Turned ON the WFS servo. The WFS output now reads in the order of 0 to +/-15.
4. Measured the MC spot positions. The spot positions look like they moved for the better compared to what they were yesterday.
