Reply to Valla's Comment on "Multiple Bosonic Mode Coupling in Electron   Self-Energy of (La_{2-x}Sr_x)CuO_4"
  From consistency among different measurements, new measurements with better energy resolution, as well as simulations, we show that the fine structure we have identified in the electron self-enery of LSCO is intrinsic, not due to random noise as Valla speculated.
