  It seems clear that the critics’ results were far more credible than Weber’s. They had checked their results by independent confirmation, which included the sharing of data and analysis programs. They had also eliminated a plausible source of error, that of the pulses being longer than expected, by analyzing their results using the nonlinear algorithm and by explicitly searching for such long  pulses.[9]  They had also calibrated their apparatuses by injecting pulses of known energy and observing the output.
