A^{μ}_{α} = 
 where C = cosh φ and S = sinh φ . 
For a motionless point change at the origin sufficient to produce a field of magnitude 1 at distance 1 the field is:
F^{αβ} = (x^{2} + y^{2} + z^{2})^{−3/2} 

F'^{μν} = (x^{2} + y^{2} + z^{2})^{−3/2} 

F'^{μν} = ((Cx' − St')^{2} + y'^{2} + z'^{2})^{−3/2}
