Scan maps (unit 105 detector counts) after line-by-line background subtraction of the down-sampled datasets (in Fig. S2). (b) Scan maps (unit 105 detector counts) after radial path-length normalization of the background data [in Fig. 2(a)]. The visualized range of values between the minimum and maximum are the same for each sample in (a) and (b). |
