[Crater-team] LRO Slew Requirements Document - internal Review

[Harlan Spence]

Thanks, Jody.  Ralph and company will be happy with our report.  Its nice when we can make someone else’s job easier without affecting the quality of net outcomes.

All of our slews will be large slews, but we only do one slew per orbit anyways, so the latter restriction isn't a problem.  During target-quiet periods when other instruments don't need any slews, we could potentially get in several slews in a single day.
