Hello all,
I working on a project and I need plot only stars in a map from an observer
located on Earth.
I have found some VSOP87 transformation matrices and I would like to know
if I will need such transformation for my case. Asking this because I have
searched VSOP87 and it seems it is related to planets location and I will
not plot planets. Or I am wrong?
matEquinoxEquToJ2000 = matVsop87ToJ2000 * getRotEquatorialToVsop87();
matJ2000ToEquinoxEqu = matEquinoxEquToJ2000.transpose();
matJ2000ToAltAz = matEquinoxEquToAltAz*matJ2000ToEquinoxEqu;
Can anyone explain the function of getRotEquatorialToVsop87()?
Thanks
Andre
