We show that thermal effects play a relevant role in the determination of the electron-phonon couplings based on the intensity of the phonon-shakeup peaks in photoemission spectra. In particular, we re-consider the determination of the electron-phonon couplings of fullerene based on a fit of the photoemission spectrum of C60- in gas phase [Gunnarsson PRB 1995]. We show that taking thermal effects into account reduces the obtained couplings by approximately 10%.
