Error distribution of the longitudinal magnetic field calculated from 15 000 synthetic Stokes profiles by the magnetic OMP method (left) and the center-of-gravity (COG) method (right). Both methods show very good accuracy with a mean absolute percentage error of 1.87% (magnetic OMP) and 1.79% (COG).
