+
+  Compute the E-terms (elliptic component of annual aberration)
+  vector (double precision)
+
+  Given:
+     EP      dp      Besselian epoch
+
+  Returned:
+     EV      dp(3)   E-terms as (dx,dy,dz)
+
+  Note the use of the J2000 aberration constant (20.49552 arcsec).
+  This is a reflection of the fact that the E-terms embodied in
+  existing star catalogues were computed from a variety of
+  aberration constants.  Rather than adopting one of the old
+  constants the latest value is used here.
