palPrenut 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
