Caption: Figure 6.
Ratios between the phase-resolved and background-subtracted XIS and HXD spectra of 4U 1626−67 and those of the Crab Nebula. The XIS source data were normalized using the canonical model of the Crab Nebula since spectra from the Crab Nebula suffer from pile-up. Phases are indicated in the same manner as Figure 5, but are offset by multiples of 10 −1. Arrows denote the upper limit.
