TIME SCALES AND COORDINATE SYSTEMS, Section B
-
Page B6, The equation of the equinoxes and the paragraph following should read:
equation of equinoxes = 1/15(Δψ cos ε + 0.002 64" sin Ω + 0.00 063" sin 2Ω)
and Δψ is the total nutation in longitude, ε is the mean obliquity of the ecliptic and Ω is the mean longitude of the ascending node of the Moon. The equation of the equinoxes is tabulated on pages B8-B15 at 0hUT for each day and should be interpolated to the required time if full precision is required.
