Caption: Figure 10.
Time-integrated spectra of X-ray emission originated from an axisymmetric shock. The dashed curve represents a blackbody spectrum at a temperature of ﹩{k}_{{\rm{B}}}{T}_{{\rm{b}}}﹩. The gradients of the straight lines are −2.0 and −2.6, which correspond to the ﹩\pm 1\sigma ﹩ values of those of the observed Swift/XRT spectrum.
