This article was originally published with an error in the main text. The original sentence, “The on-resonance intensity includes a charge order contribution (grey shaded region, Fig. 2b), which disappears on a timescale shorter than that of the off-resonance intensity and is sensitive only to structural dynamics”, should have read: “The on-resonance intensity includes a charge order contribution (grey shaded region, Fig. 2b) that disappears on a timescale shorter than that of the off-resonance intensity, which is sensitive only to structural dynamics.”

We apologize to the readers for this error.
