[VA] SRC #012f - Then and Now: Angle

[Gjermund Skailand]

Dear Valentin,

Thanks for the challenges.
For me, the last one was very interesting, as I have been curious about "rocket science". Probably the low number of replies to the last problem is simply that summer is coming, and also that integration (R_K) seemed to and turned out to work so well. Further, thanks to J-F for showing the paths.
Is it possible to calculate longer paths, say circling the star cluster once twice, or would numerical inaccuracies quickly make any such results rubbish?
