Gravityfield2Deflections
This program computes the deflections of the vertical $\xi$ in north direction and $\eta$ in east direction in radian according to \[ \xi = g_x/\gamma \qquad\text{and}\qquad \eta=g_y/\gamma, \]where $\M g=\nabla V$ is the gravity vector from gravityfield in the local ellipsoidal system (north, east, up) and $\gamma$ is the normal gravity at that point.
The values will be saved together with points expressed as ellipsoidal coordinates (longitude, latitude, height) based on a reference ellipsoid with parameters R and inverseFlattening.
