Otherwise, the changing distances are due to the optimization of SROIs to target the nominal magnetopause and model neutral sheet (also the bow shock, conjunctions with other missions, avoidance of eclipses, etc).

In addition, the POC adds the following:

• FPI Calibrations will be scheduled on either outbound/inbound leg, or both, based on time available (time between SROI and L6)
  SROI definitions are created so that there will be an FPI calibration on at least one leg, and POC confirms this when receiving/processing them.
  POC screens ATS products to make sure that the ASPOC Current Sweep calibration does not overlap the FPI Calibration, we do not have a constraint against ASPOC being in Active during an FPI Calibration

Why must we have three SROI?
