Left: Mass positions for PCM-EMC (blue) and EMC (green) after applying the nonlinearity correction obtained from Sec. 4.3.2 Fig. 41. The mass positions are normalized to the neutral pion rest mass. In the case of PCM-EMC the data points represent the squared mass position. Right: Ratio of mass positions in data and MC for both techniques with their corresponding fits according to Eq. 27.
