Left: calibrated ugriz light curves from Keck LRIS spectrophotometry (filled dots) and direct imaging (open dots). Outlier points excluded in the “trimmed” model fitting are indicated by orange crosses. The curves show the best-fit ugriz models and the dotted line marks pulsar inferior conjunction. Right: residuals to the best model fit. Optionally excluded points are again marked by orange crosses. The spectra used for Figures 1–3 are available as data behind the Figure.
