Full PDCSAP light curve of β Pictoris used in this analysis. The red vertical lines indicate the starts of Sectors 4 through 7. The black triangles point to the three identified decreases in flux, labelled A,B,C in decreasing signal to noise. The time of momentum dumps are indicated with red triangles; a small change in spacecraft pointing at the beginning of Sector 4 (due to an updated guide star table) is shown with a blue triangle.
