Files are comma delimited '*.dat' files containing data from figures in the paper and supplementary information.

Paper
	Figure 2a-c	-	THz time domain scans of In2Se3+Pt as a function of sample rotation
	Figure 2d 	-	THz time domain scans of In2Se3 & In2Se3+Pt as a function of sample tilt
	Figure 3a	- 	THz time domain scans of In2Se3+Pt with the sample flipped and not flipped
	Figure 3b 	- 	THz time domain scans of In2Se3+Pt and In2Se3+W
