Totaling 575 successful visits, this is the largest such campaign reported to date. Variations within the UV/optical are well-correlated, with longer wavelengths lagging shorter wavelengths in the direction predicted by thin disk/lamp-post models. The correlations are improved by detrending; subtracting a second-order polynomial fit to the UV/optical light curves to remove long-term trends that are not of interest to this study. Extensive testing indicates detrending with higher-order pol","authors_text":"B. M. Peterson, I. McHardy, J. Gelbord, K. Horne, M. Goad, M. Vestergaard, R. Edelson, S.
