Energy spectra of EXO 2030+375 obtained with the XIS, PIN, and GSO detectors of the Suzaku observation at the peak of the type I outburst, along with the best-fit model consisting of a partially absorbed power law with a high-energy cutoff continuum model with a neutral absorber. Five emission lines (as given in Table 1) are detected in the broadband spectrum of the pulsar. The contributions of the residuals to the χ ² for each energy bin for the best-fit model are shown in the bottom panel.
