Caption: Figure 2.
Upper Panel: The normalized intensity pulse profile of 1E 1841−045 from 2 to 8 keV using observations from NICER preceding the outburst. Second Panel: The source 2–8 keV intensity pulse profile post-outburst as observed with IXPE. Third Panel: The post-outburst pulse profile from 3 to 10 keV observed simultaneously by NuSTAR. Bottom Panel: The NuSTAR 10–70 keV pulse profile.
