1.6 for

Widget makes airmass plots easily.

AstroAirmass is designed to make airmass plots easy. Resolve an object name through SIMBAD or put coordinates, choose an observatory and a date, and go! If you have the Python module ?'biggles?" installed, you can save the plot and open it with Preview. Drop me a mail to add your plotting script (e.g. in Perl). (Known issues: no real input validation, very limited canvas management.)
Release Notes Version 1.6: More observatory, and a fix of a dirty bug. New: CARMA, Dome C, Picos dos Dias.
