IC radiation light curve from upscattering of UV photons in comparison with observations. The upper panel is for fixed ﹩{\beta }_{0,-2}=3﹩ but varying A: ﹩{A}_{38}=0.3﹩, 0.7, and 1.5 for dashed, solid and dashed-dotted lines, respectively. The lower panel is for fixed ﹩{A}_{38}=0.7﹩ but varying β₀: ﹩{\beta }_{0,-2}=1﹩, 3, and 8 for the green dashed, solid and dashed-dotted lines, respectively. The red stars are the X-ray data. The blue dots show the evolution of bolometric luminosity, and the red solid line shows the fitting function. The other parameters used are ﹩{\epsilon }_{{\rm{e}}}=0.1﹩ and p = 3.
