Use this to check for an RV fudge for Keck
Keck is performing much worse than APF. Here is an iGrand vs. Keck RMS comparison:
The CPS velocities (MNVEL) show lower RMS in many cases. The large iGrand RMS for some stars is driven by terrible systematics w/ BC. e.g. 144579:
Here is what the double fudge looks like for Keck.
Self-explainatory. Run some stars from the APF-50 sample.
