From these we construct the frequency-centered light curves with an emphasis on the X-ray and optical bands. &lt;BR /&gt; Results: We show that in cases where γ&lt;SUB&gt;max&lt;/SUB&gt; takes low values, the produced X-ray light curves show a plateau as the synchrotron component gives its place to the synchrotron self-Compton one in the X-ray band.</style></abstract></record></records></xml>
