We consider an α-57Fe sample of 2.3 μm with an aligned magnetization and an analyzer of 1 μm effective thickness. a Input 2D time- and energy-dependent intensity data set. The color code displays the natural logarithm of the signal. This set is then reconstructed via b NPRS and c phase determination in the time ___domain (PDTD). d Measurement error of NPRS as a function of iteration step. e NPRS spectral intensity of the sample as a function of detuning. For comparison, we present here also the PDTD and scaled time-integrated spectroscopy (TIS) spectra in arbitrary units. f Recovered phase using NPRS and PDTD. g Relative error of the recovered spectrum using NPRS as a function of the retrieval iteration step.
