For the R-band light curve (a), the γ-ray light curve (b) and the fractional polarization curve (c). Black contours in a and b indicate periods significant at the 99% level; grey contours in c indicate periods significant at the 92% level. Dashed white curves represent a cone of influence (COI), in which the information outside is affected by edge artefacts; numbers near contours indicate some periods for clarity.
