Summary of the SNRs of RS (SNR_RS) and CWEPR (SNR_CW) spectra after digital low-pass filtering for all samples under study. The SNRs were computed as maximum signal amplitude for RSEPR, or peak-to-peak height for CWEPR, respectively, divided by RMS noise. Values are normalized to an acquisition time (T_acq) of 1 s by dividing by $\sqrt{T_{\text{acq}}}$.
