I guess this needs fixing because of the discussion in the irc channel:

[22:49:32] <kstar> tsdgeos: Oh, I meant to tell you that I had some complaints with that.
[22:49:43] <kstar> tsdgeos: Including the fact that the lunar eclipse calculations are in principle incorrect.
[22:50:07] <kstar> tsdgeos: I'm sorry I cannot be active on KStars anymore. hdevalence seems to have more time than me these days.
[22:50:37] <kstar> vijay13: When you're computing a lunar eclipse, the diameter for the conjunction has to be the size of the umbra of the earth.
[22:50:44] <kstar> i.e. the angle subtended by the earth at the moon.
[22:51:23] <kstar> So you can calculate oppositions, but the tolerance must be (if I understand correctly), the diameter of the sun at the moon + the diameter of the earth at the moon or something like that.
[22:52:41] <vijay13> kstar: seems logical what you saying , I am ashamed of maself ;-) i just used shortway that time
