The quantity δg _Bc (≡ 2πGh² ρ/2a) representing the force per unit mass, or acceleration, caused by the attraction of a cylindrical solid of density ρ, radius a and height h on a unit mass located at the intersection of the cylinder's axis with the top surface. G is the gravitational constant. The cylindrical Bouguer gravity correction is used in calculating Faye's gravity anomaly.
