+ SUBROUTINE slNUTC (DATE, DPSI, DEPS, EPS0)
+*+
+* - - - - -
+* N U T C
+* - - - - -
+*
+* Nutation: longitude & obliquity components and mean obliquity,
+* using the Shirai & Fukushima (2001) theory.
+*
+* Given:
+* DATE d TDB (loosely ET) as Modified Julian Date
+* (JD-2400000.5)
+* Returned:
+* DPSI,DEPS d nutation in longitude,obliquity
+* EPS0 d mean obliquity
+*
+* Notes:
+*
+* 1 The routine predicts forced nutation (but not free core nutation)
+* plus corrections to the IAU 1976 precession model.
+*
+* 2 Earth attitude predictions made by combining the present nutation
+* model with IAU 1976 precession are accurate to 1 mas (with respect
+* to the ICRF) for a few decades around 2000.
+*
+* 3 The slNUTC80 routine is the equivalent of the present routine
+* but using the IAU 1980 nutation theory. The older theory is less
+* accurate, leading to errors as large as 350 mas over the interval
+* 1900-2100, mainly because of the error in the IAU 1976 precession.
