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

[Jody Wilson]

Hi Harlan,

The restriction of seven slews per day of 5° or more, and one large slew 
(>20°) per orbit, aren't new.   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.

Regarding all the checks that have to be done before a slew is approved 
- the new added complexity supports our case of asking the MOT to just 
fit in our simple fixed-angle horizon slews whenever the opportunity 
presents itself, just like they do for pulser sequences and used to do 
for the 90° cal slews.

-Jody
