pget_mean_obliquity

static double pget_mean_obliquity(double t)

The obliquity formula (and all the magic numbers below) come from Meeus, Astro Algorithms.

Input t is time in julian day. Valid range is the years -8000 to +12000 (t = -100 to 100).

return value is mean obliquity (epsilon sub 0) in degrees.
