Each text file contains the data-set used to produce the relevant figure (see file name). You can find the data to produce A.4. online at  https://avaa.tdata.fi/web/smart/smear/ 

Please pay attention to the following before using this data.

1. Figure2_lampRadPanel_Wm2srnm.txt: Note that the shapes are of interest here. The magnitude is not the same as the incident light at top of canopy, as these spectra were measured in a laboratory. See paper section A.1. for more details. 
2. Figure3_LEDIFspectra_Wm2srnm.txt: This data contains the whole observed spectrum including the non-fluorescence regions, which were saturated (warped) in the visible. The fluorescence region is approximately > 650 nm.   
3. Figure4_AQYspectra_nm.txt: As with Figure3 the whole spectrum is included here.
4. FigureA3_repLEDIFspectra_[pmay/psep/usep]._nm.txt:  Data from which the mean spectra (Figure3) were calculated, including the uncorrected red spectra. I have split these by canopy type to avoid name conflicts.
