choclo.point.gravity_en(easting_p, northing_p, upward_p, easting_q, northing_q, upward_q, mass)[source]#

Easting-northing component of the gravitational tensor due to point source.

Returns the easting-northing component of the gravitational tensor produced by a single point source on a single computation point

Parameters:
easting_p, northing_p, upward_pfloat

Easting, northing and upward coordinates of the observation point in meters.

easting_q, northing_q, upward_qfloat

Easting, northing and upward coordinates of the point source in meters.

massfloat

Mass of the point source in kilograms.

Returns:
g_enfloat

Easting-northing component of the gravitational tensor generated by the point source on the observation point in s2.

Notes

Returns the easting-northing component gxy(p) of the gravitational tensor T on the observation point p=(xp,yp,zp) generated by a single point source located in q=(xq,yq,zq) and mass m.

gxy(p)=Gm[3(xpxq)(ypyq)pq25]

where 2 refer to the L2 norm (the Euclidean distance between p and q) and G is the Universal Gravitational Constant.
