DQ Tau UBVR light curves plotted against (arbitrary) orbital cycle number. LCOGT, ARCSAT, and WIYN 0.9 m data are represented as crosses, circles, and triangles, respectively. ARCSAT data are transformed from SDSS to Johnson filters. Vertical dashed lines mark periastron passages. Note the difference in the y-axis scale for different filters. The large error bar in the top right of each panel represents the systematic error in our photometric calibration.

(A machine-readable table of the data presented in this figure is available in the online journal.)
