Description:
Transform from ecliptic coordinate to J2000.0 equatorial coordinates.
Invocation
void palEcleq ( double dl, double db, double date, double
∗dr, double
∗dd );
Arguments
dl = double (Given)
Ecliptic longitude (mean of date, IAU 1980 theory, radians)
db = double (Given)
Ecliptic latitude (mean of date, IAU 1980 theory, radians)
date =
double (Given)
TT as Modified Julian Date (JD-2400000.5). The difference between TT and
TDB is of the order of a millisecond or two (i.e. about 0.02 arc-seconds).
dr = double
∗ (Returned)
J2000.0 mean
RA (radians)
dd = double ∗
(Returned)
J2000.0 mean Dec (Radians)
