Extended Data Fig. 4: Amplitude of the principal components.
From: Ultrafast X-ray imaging of the light-induced phase transition in VO2
a Relative amplitude of the principal components considering only data in the first picosecond (truncated) and including data at 250 and 500 ps (with long times). Also shown is the noise floor. b,d PC1 (top) and PC2 (bottom) using truncated time data. c,e PC1 and PC2 including data out to 500 ps.
