• In the case of correct triclinic anisotropy with rotation of the tensor of elastic moduli around axes x₁ and x₃, the migrated interface in the final stacked image coincides nearly perfectly with the interface in the model used to compute the recorded wave field.

  For rotation around the axis x₂ we observed unexpected nearly vanishing part of the migrated interface (Bucha, 2013b).

• In the case of incorrect triclinic anisotropy without the rotation of the tensor of elastic moduli, the errors of the migrated interface depend on the axis around which we rotate and on the rotation angle. The errors increase with the angle of the rotation for all rotation axes.
