Deriving absolute value of the magnetic field strength from I and V stokes parameters
In this work, we describe a simple technique to evaluate the absolute value of the magnetic field strength from I and V Stokes parameters. The absolute value of the vector magnetic field can be derived from the extrema positions of Stokes V profile. One can simply evaluate the modulus of the transversal magnetic field from these two quantities. The spectropolarimetric data acquired by Hinode were used to test the technique proposed. Our results are in a good agreement with the magnetic field measurements provided by the Hinode team.
