palNutc
palNutc
- Calculate nutation longitude & obliquoty components
- Description:
- Calculates the longitude
obliquity components and mean obliquity
using the SOFA library.
- Invocation:
- void palNutc( double date, double
dpsi, double
deps, double
eps0 );
- Arguments:
-
-
date = double (Given)
-
TT as modified Julian date (JD-2400000.5)
-
dpsi = double
(Returned)
-
Nutation in longitude
-
deps = double
(Returned)
-
Nutation in obliquity
-
eps0 = double
(Returned)
-
Mean obliquity.
- Notes:
- Calls iauObl06 and iauNut06a and therefore uses the IAU 206
precession/nutation model.
- Note the change from SLA/F regarding the date. TT is used
rather than TDB.
