epsa
[SOFA] Returns the IAU 2006 precession angles for TT Julian Date
jdtt
in Fukushima-Williams 4-angle formulation: f-w angle
gamma_bar in radians gamb
, f-w angle phi_bar in radians
phib
, f-w angle psi_bar in radians psib
, f-w
angle epsilon_a in radians epsa
. The four output
variables get the same dimensions as jdtt
.
