Ecliptic Declinations and Right Ascenesions.

According to Eqs. (38) and (39), the celestial coordinates of a point on the ecliptic circle (i.e., $\beta = 0$) which has ecliptic longitude $\lambda$ are specified by

$$\sin\,\delta = \sin\epsilon\,\sin\lambda,$$ (40)

$$\tan\,\alpha = \cos\epsilon\,\tan\lambda.$$ (41)

The above formulae have been employed to construct Tables 5 and 6, which list the declinations and right ascensions of a set of equally spaced points on the ecliptic circle.
