Hi there, I have some doubts about Target in Planet Approach.

While in the manuals it's well described how to set it, I find difficult to find examples on targets different from "l" (equatorial).

The other options are "e" (ecliptic), "r" (reference planet), "g" (geostationary), but changing targets doesn't change any parameters on Planet Approach.

To be more precise:
"g" (geostationary) and "l" (equatorial) seem to be exactly the same, no parameters change (as it should be, right?).
"r" (reference planet) and "e" (ecliptic) seem to be exactly the same, no parameters change.

If we compare "g" (or "l") with "r" or "e", EqI and EqI limits remain the same, but change EIn, RIn and AgP, as well the line of plane intersection.

Beside a theoretical explanation (always welcome):tiphat:, do you have any practical examples / purposes for all type of targets?
