Bob,
Yes, within the yearly information header of my WWW Solar Calculator
(URL below) I report the true obliquity at JAN 1.0 of the year being
evaluated (the longitude of perihelion as well as the date/times of the
solstices/equinoxes for the year are included too). So if you just need
to

See "Astronomical Algorithms" by Jean Meeus, pp 135-6. It is recommended
for astronomical calculations. The "Astronomical Almanac" probably has
values also.
The mean obliquity is (defined by the International Astronomical Union):
23 deg 26'21".448 - 46".8150 T - 0.00059 T^2 + 0".001 813 T^3
Hi All,
Comment: I think the problem with rotating or skewing text in graphics
files could be solved if the text character entities could be converted
into the vector lines and curves which make them up. I don't think this
is easy to do with True Type fonts.
Question: Is there a source, or value
