Dear Users:
1. New functions OrbitGeo and GeoBase are introduced.
OrbitGeo[location] returns the geometry {GX, GY, GZ}
of the current (not design) orbit.
GeoBase[{chi1, chi2, chi3}] converts the rotation angles
of the coordinate base vectors to a transformation
matrix {{x_gx,x_gy,x_gz}, {y_gx,y_gy,y_gz}, {z_gx,z_gy,z_gz}}.
2. A bug in RADLIGHT tracking when EPS is small and the number of
the resulting points of the trajectory is large.
3. Now MULT with ANGLE supports RADLIGHT.
