Several of the lower mode shapes of the model are available for viewing.
The moments of inertia of the results given below were calculated about the model's origin, which is located on the optical axis at the midplane of the honeycomb support panel (see the exploded view for the exact location). There is also a need for the effective weight information with the origin located in the plane where the feet meet the Nadir Panel (i.e., the spacecraft). That information is also available by downloading the file basemode.txt.
