Function Documentation

Mat3d lupnt::RotMoonPaToMe()

Returns the constant (time-independent) MoonPa-to-MoonMe frame-bias rotation matrix B_moon, built from the IAU mean-Earth/polar-axis offset angles, such that v_ME = B_moon * v_PA.

Used internally by MoonPaToMe/MoonMeToPa to convert between the Moon-fixed principal-axis (PA) and mean-Earth/polar-axis (ME) frames.

Returns:

3x3 MoonPa-to-MoonMe frame-bias rotation matrix B_moon (dimensionless)
