Fig. 11.
Cutoff energy Ecut versus cyclotron line energy Ecyc for objects studied by RXTE (Coburn et al. 2002) and BeppoSAX (Doroshenko 2017). The cutoff energy is roughly proportional to the square root of Ecyc. The two objects 4U 1744-28 and 4U 1626-67 are extreme outliers to this relationship, and not included in the fit.
