The NLS coordinate system is defined as follows: - X lies in the equatorial plane of Neptune, positive away from the planet, and through the prime meridian. - Z is parallel to the Neptune spin axis, and, - Y is X x Z (lefthanded) The prime meridian of the this system is defined such that at 1989-08-25T03:56:00.000 the Voyager 2 spacecraft was at 167.7 degrees west longitude. For the PDS archive dataset, the original data archive has been converted to an east longitude (righthanded) coordinate system minus NLS (-NLS). This is achieved by reversing the direction of the Y-axis or in spherical coordinates, subtracting the NLS longitude from 360.0 degrees.
