Terminology The following terms are used:
where ΞπΏπ= πΏ π΄ cos π π΄ β πΏ π΅ cos π π΅ πΏ π΄ sin π π΄ β πΏ π΅ sin π π΅ πΏ= π cos π 2 π= π₯ 2 + π¦ 2 + π§ 2 π= atan π§ ππ π₯ ππ 2 + π¦ ππ 2 π= atan π₯ ππ π¦ ππ and SM denotes a coordinate in the solar magnetic system, and A and B refer to the two spacecraft. The difference in values is taken with B subtracted from A: βF(x) = βF(xA) - βF(xB)
