Figure 6From: Performance analysis of an optically pumped magnetometer in Earth’s magnetic fieldFWHM of the magnetic resonances as a function of the angle α. Again diamonds and dots correspond to the use of x and y coil for applying the rf-field, respectively. In green, we added the corresponding difference between \(\sigma _{+}\) and \(\sigma _{-}\) result. The solid lines correspond to calculation results following Eq.
