OPM resonances. Cesium resonances, acquired with the lock-in amplifier at different background magnetic fields. (a) Magnitude (LIA-R), (b) quadrature component (LIA-Y); The frequency axes are centered at the Larmor frequency. The region of linear Y-response used for data analysis is marked by black dotted lines
