Description of symmetrical prolate ellipsoid (sphere) magnetic signature parameters-Be = 50 mT, I = 70 deg, z = -10 m, a =4 m, e = 1, mr = 100

The Earth magnetic field (Fig.1): BE – total magnetic flux density, BEx – x component of the Earth magnetic flux density, BEy = 0 y component of the Earth magnetic flux density, BEz – z component of the Earth magnetic flux density, I – inclination of the Earth magnetic field. The symmetrical prolate ellipsoid (Fig.2): L – length of ellipsoid, a – radius of ellipsoid, e – unidimensional coefficient, q - vertical angle, j - horizontal angle. For sphere e=1. For each scenario there are following files: Ind_Bx_[BE]_[I]_[z]_[a]_[e]_[mr] Bx – component of the ellipsoid magnetic flux density [nT] Ind_By_[BE]_[I]_[z]_[a]_[e]_[mr] By – component of the ellipsoid magnetic flux density [nT] Ind_Bz_[BE]_[I]_[z]_[a]_[e]_[mr] Bz – component of the ellipsoid magnetic flux density [nT] Ind_x_[BE]_[I]_[z]_[a]_[e]_[mr] x coordinate [m] Ind_y_[BE]_[I]_[z]_[a]_[e]_[mr] y coordinate [m] were: BE [mT], I [deg], z [m], mr – relative magnetic permeability Ind – induced magnetization of sphere For the following parameters: Be = 50 mT, I = 70 deg, z = -10 m, a =4 m, e = 1, mr = 100 The names files are: Ind_Bx_50_70_10_4_1_100 Bx – component of the ellipsoid magnetic flux density [nT] Ind_By_50_70_10_4_1_100 By – component of the ellipsoid magnetic flux density [nT] Ind_Bz_50_70_10_4_1_100 Bz – component of the ellipsoid magnetic flux density [nT] Ind_x_50_70_10_4_1_100 x coordinate [m] Ind_y_50_70_10_4_1_100 y coordinate [m] For the following parameters: Be = 50 mT, I = 70 deg, z = -10 m, a =4 m, e = 1, mr = 500 The names files are: Ind_Bx_50_70_10_4_1_500 Bx – component of the ellipsoid magnetic flux density [nT] Ind_By_50_70_10_4_1_500 By – component of the ellipsoid magnetic flux density [nT] Ind_Bz_50_70_10_4_1_500 Bz – component of the ellipsoid magnetic flux density [nT] Ind_x_50_70_10_4_1_500 x coordinate [m] Ind_y_50_70_10_4_1_500 y coordinate [m]
