Description of parameters of symmetrical prolate ellipsoid magnetic signature.

Description

The Earth magnetic field (Fig.1): B_E – total magnetic flux density, B_Ex – x component of the Earth magnetic flux density, B_Ey = 0 y component of the Earth magnetic flux density, B_Ez – 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 each scenarios there are following files:

Ind_Bx_[B_E]_[I]_[z]_[q]_[j]_[a]_[e]_[m_r] B_x – x component of the ellipsoid magnetic flux density [nT]

Ind_By_[B_E]_[I]_[z]_[q]_[j]_[a]_[e]_[m_r] B_y – x component of the ellipsoid magnetic flux density [nT]

Ind_Bz_[B_E]_[I]_[z]_[q]_[j]_[a]_[e]_[m_r] B_z – x component of the ellipsoid magnetic flux density [nT]

Ind_xy_[B_E]_[I]_[z]_[q]_[j]_[a]_[e]_[m_r] x+jy – point coordinates [m] j = -1^0.5
