Caption: Figure 11.
Shown here are special ﹩{\phi }_{* }﹩-integrated spectra, with shadowing, for instantaneous ﹩{\theta }_{v}=30^\circ ﹩, ﹩{B}_{p}=10﹩, ﹩{r}_{\max }=4﹩ and fixed and uncooled ﹩{\gamma }_{e}={10}^{2}﹩. For all ﹩{\theta }_{v}\gt 0﹩ examples, the flat spectrum is reminiscent of uniform field spectra presented in Baring & Harding (2007) that accessed all final scattering angles. Compared to meridional spectra shown in Figures 6, 8, and 9, here the spectrum is steeper by a factor of ﹩\sim {\varepsilon }_{f}^{-1/2}﹩ owing to the strong beaming of the hardest emission observed only near meridional field loops. The ﹩{\theta }_{v}=0^\circ ﹩ example is a symmetric case where the spectrum is independent of the azimuth, and so it is flatter, resembling those in earlier figures. The two vertical dashed lines mark the energies 16 and 100 keV that correspond to the pulse phase maps in Figure 12.
