Why does the LP_Factor_X macro split out one of the Sin(Th) to have in a scale_pks equation? Wouldn't it all work in the scale_phase_X equation?
macro LP_Factor_X(c, v)
{
#m_argu c
If_Prm_Eqn_Rpt(c, v, min .0001 max 90)
local #m_unique th = X Pi / 360;
scale_phase_X = (1 + Cos(c Deg)^2 Cos(2 th)^2) / (Sin(th) Cos(th));
scale_pks = 1 / Sin(Th); 'why is this here?
}
