The opportunity windows for JMAG calibration rolls are defined as:
Interval |B|> 100 nT for more than 12 hours (Use Khurana model or/and latest B model from Juno (Jupiter intrinsic) )
the local magnetic field strength is not varying by more than 10 nT over each of the six 2 hour-windows (within the 12 hours).
At least one of those 2hour windows is not varying by more than 5 nT.
5 rolls in total should be scheduled during the tour: 2 as soon as possible after JOI, 2 right before GOI and one in the middle
assuming:
JMAG: 2.31 kbps
RPWI: 1.7*2.167 kbps
PEP: 2 kpbs (ball park number; discussion with Gabriella at WG3 F2F meeting in Sept 2018)
SWI monitoring of the moons no included for now. (as per spreadsheet)

From case #5/6 onward:
moniroting rate for in-situ 7.36 kbps
SWI monitoring 0.33 kbps
