Produced Aug
Justin Atchison and Fazle Siddique

2. Terminology The following terms are used:
where
Δ𝐿𝜙= 𝐿 𝐴 cos 𝜙 𝐴 − 𝐿 𝐵 cos 𝜙 𝐵 𝐿 𝐴 sin 𝜙 𝐴 − 𝐿 𝐵 sin 𝜙 𝐵
𝐿= 𝑟 cos 𝜆 2
𝑟= 𝑥 2 + 𝑦 2 + 𝑧 2
𝜆= atan 𝑧 𝑆𝑀 𝑥 𝑆𝑀 2 + 𝑦 𝑆𝑀 2
𝜙= atan 𝑥 𝑆𝑀 𝑦 𝑆𝑀
and SM denotes a coordinate in the solar magnetic system, and A and B refer to the two spacecraft.
