Scientific Reports 5: Article number: 14834; published online: 06 October 2015; updated: 10 June 2016.

This Article contains errors in Figure 1: the coloured axes have been inverted. The correct Figure 1 appears below. As a result, the Figure legend,

“recorded at time delays of 100 ps (green squares, left vertical axis)16 and 1 ps (this work, blue dots, right vertical axis).”

should read:

“recorded at time delays of 100 ps (green squares, right vertical axis)16 and 1 ps (this work, blue dots, left vertical axis).”
