From Noise analysis to Error Bars on Refractive Index In THz-TDS

We present a new methodology for computing error bars in THz-TDS experiments and distribute open source software for this purpose. Pursuing our efforts in noise analysis and data processing of THz-TDS experiments, we followed a standard approach to derive the error bars from the simplest quantities coming from the experiments (transmission, absorbance) and a Bayesian approach when using an optimization fitting methodology to retrieve the plotted magnitude (refractive indices).
