+ SUBROUTINE slSUET (RC, DC, EQ, RM, DM)
+
+ - - - - - -
+ S U E T
+ - - - - - -
+
+ Remove the E-terms (elliptic component of annual aberration)
+ from a pre IAU 1976 catalogue RA,Dec to give a mean place
+ (double precision)
+
+ Given:
+ RC,DC dp RA,Dec (radians) with E-terms included
+ EQ dp Besselian epoch of mean equator and equinox
+
+ Returned:
+ RM,DM dp RA,Dec (radians) without E-terms
+
+ Called:
+ slETRM, slDS2C, sla_,DVDV, slDC2S, slDA2P
+
+ Explanation:
+ Most star positions from pre-1984 optical catalogues (or
+ derived from astrometry using such stars) embody the
+ E-terms. This routine converts such a position to a
+ formal mean place (allowing, for example, comparison with a
+ pulsar timing position).

+ Reference:
+ Explanatory Supplement to the Astronomical Ephemeris,
+ section 2D, page 48.
