> Chelle says we don't need to do flatSat testing on the Oxygen mode because that's already been done. Therefore, for the moon test, the idea is to operate the sensor in the standard spring ISN mode. No exceptions! Chelle also said that there would be a difference in the spin axis direction because of a star tracker outage, but that difference (as near as I can figure) is only about a half a degree on the sky. Since we hang out a apogee and the moon moves into and out of the field of view, that would only change the start/stop times, so I added an hour on either end.

> For the background test, we would like to be in the magnetosheath. So the following orbit (Orbit 84) might be a good one to do the test. 
> That is even simpler, we would use the LUT 255 (energy step "0") and we would do that for all angles all the time. A good day's worth of data say starting a half day post perigee would do the trick.
