Gravitational acceleration, gravitational potential, slope, and elevation

Gravitational acceleration, gravitational potential, slope, and elevation plate data can be viewed when clicking the "Standard" radio button within the Plate Coloring section of the leftmost tab of each shape model.

Gravitational acceleration data and gravitational potential data was calculated using an in-house implementation of either the algorithm of Werner and Scheeres (Werner, R.A. and Scheeres, D.J., 1997, Exterior gravitation of a polyhedron derived and compared with harmonic and mascon gravitation representations of asteroid 4769 Castalia, Celestial Mechanics and Dynamical Astronomy, Vol. 65, pp. 313-344) or the algorithm of Andy Cheng (Cheng, A.F. et al., 2012, Efficient Calculation of Effective Potential and Gravity on Small Bodies, ACM, 1667, p. 6447). The acceleration and potential were evaluated at each plate center using one of these algorithms. Also, an additional term was added to both the potential and acceleration to correct for the rotation of the small body. Values of densities and rotation rates were obtained from various sources.
Slope data was computed as the angular separation in degrees between the plate normal vector and the negative gravitational acceleration vector (computed as explained above) at each plate center.
Elevation data was computed as follows. First a reference potential R was selected. The reference potential was either chosen to be the minimum potential across all plates, or the average potential weighted by the plate area, i.e., R = SUM(P_i*A_i)/SUM(A_i) where P_i is the potential at the center of the ith plate, A_i is the area of the ith plate, and where the sum is over all plates. Having established the reference potential R, the elevation E was computed as: E = (P_i-R)/g, where g is the magnitude of the acceleration vector at the ith plate center.
