Notes. X, Y, Z are Heliocentric Galactic Cartesian coordinates; Xg, Yg, Zg are Galactocentric Cartesian coordinates; and are transformed Cartesian coordinates with the X-axis pointing toward a central position in Orion (toward l, b = 206.038° ,−21.945°). The last three columns are Galactic Cartesian velocities relative to the LSR.
