Well, I didn't exactly notice it after I pressed the SEND button, but
just after I got my first really unreasonable results... :-)

The 360 was supposed only in the case I was calculating angular
separation between spacecraft + moon...

As for this IDL problem, maybe I don't need to fight with it anymore,
but in any case, it seems that when it changes the value from negative
to positive (by adding the 360), it somehow adds 360 for a second time
(although the if statement is not satisfied), and therefore I get these
strange values...
