palPrenut
- Form the matrix of bias-precession-nutation (IAU 2006/2000A)
- Description:
- Form the matrix of bias-precession-nutation (IAU 2006/2000A).
The epoch and date are TT (but TDB is usually close enough).
The matrix is in the sense v(true) = rmatpn
v(mean).
- Invocation:
- void palPrenut( double epoch, double date, double rmatpn[3][3] )
- Arguments:
-
-
epoch = double (Returned)
-
Julian epoch for mean coordinates.
-
date = double (Returned)
-
Modified Julian Date (JD-2400000.5) for true coordinates.
-
rmatpn = double[3][3] (Returned)
-
combined NPB matrix
