All the broadband spectra were successfully modeled by a simple analytic model, power-law with an exponential cutoff. The obtained energy cutoff($E_{\\rm{cut}}$) is distributed over 50--300 keV, and the photon index over 1.4-1.6. We found a clear correlation ($E_{\\rm{cut}}$ is proportional to $L^{-0.75 \\pm 0.04}$) between luminosity in 2-200 keV (L) and $E_{\\rm{cut}}$ when L is larger than 5$\\times 10^{37}$ erg $s^{-1}$, while $E_{\\rm{cut}}$ is almost constant at 20","authors_text":"Atsumasa Yoshida, Hajime Inoue, Kazutaka Yamaoka, Koji Saito, Tadayasu Dotani, Takehiro G.
