Fig. 4: Resolved sideband spectra.

a Resolved sideband spectrum after transport for a transport time of ttp = 7 ms without filter predistortion. b Resolved sideband spectrum after transport for a transport time of ttp = 15 ms using filter predistortion. Each data point (blue, representing the mean) and the respective error (clear blue, ± standard deviation of the mean) are obtained from 50 Raman interrogations after transport. Red lines are Lorentzian fits to the sideband data, clear blue dashed lines are Gaussian envelope fits to the sideband maxima. νRef = 138.909014 GHz is a reference frequency close to ν0.
