Left: Pulse profile in 10–20 keV bands for PSR B0540−69. The solid line is result for ﹩\alpha =30^{\circ }﹩ and ﹩\xi =98.5^{\circ }﹩ (and ﹩\xi =81.5^{\circ }﹩), and the dashed line is for ﹩\alpha =50^{\circ }﹩ and ﹩\xi =104^{\circ }﹩ (and ﹩\xi =76^{\circ }﹩). Right: Phase‐averaged spectrum of PSR B0540−69 for ﹩\alpha =30^{\circ }﹩ and ﹩\xi =98.5^{\circ }﹩ (and ﹩\xi =81.5^{\circ }﹩). The solid line represents the total emissions of the synchrotron radiation (dashed line) and the inverse‐Compton scattering (dotted line). The observation data are taken from de Plaa et al. (2003).
