This sounds to me like you're having a problem with stars that have
Decliantion between -1.0 and 0.0 degrees. For these stars, the
Declination in dd mm ss form would be expressed like this:
-00 15 45
But if you're not careful with the parsing, this will get translated
to +0.2625 degrees,
instead of -0.2625. The reason is, if you do int("-00"), that gets
turned into 0, which is not negative. The solution is to keep the
negative sign separate from the ddmmss string and add it after you've
converted to a decimal value.
regards,
Jason
