The api jupitermoons.e5() takes a mandatory earth argument. This is what one normally needs to compute transits, occultations, or just the visible positions.
However, to compute the shadow transits and eclipses, one would need to set Sun's radius vector to zero (Meeus, p. 315).
I don't see how this can be done. Am I missing something?
If not, can something be changed to allow that - e.g. ability pass a null earth argument, which would be considered as "make range be zero"?
