Position, velocity and time
Requirements: position is in degrees (though that is only required by setFromPair with isAngle=true). velocity is in degrees/unit of time. However, as used within this package, time is always TAI (MJD, seconds).

Set from a pair of positions or angles computed at different times
[in] | posPair | pair of positions, where: posPair[0] is computed at time t posPair[1] is computed at time t + deltaT |
[in] | t | time at which posPair[0] is computed |
[in] | deltaT | time difference between the two positions |
[in] | isAngle | if true then posPair values are treated as angles, in degrees, and the resulting velocity is computed using: posPair[1] - posPair[0] wrapped into the range [-180, 180) |
