Prism (pygeoid.simple.prism)

class pygeoid.simple.prism.Prism(bounds, density=1.0)

External gravitational field of the right rectangular prism.

Parameters:

• bounds ((x1, x2, y1, y2, z1, z2), floats) – West, east, south, north, top and bottom of the prism, in metres.
• density (float) – Density of the prism, in kg/m**3.

Notes

The formulas from Nagy et al.[1]_ are used in this class.
