Table 1: APO light curves for quasar images A and C. Magnitudes are shown relative to the value of the last data point of image C in the g' filter.
Table 2: Local macro-lensing parameters for quasar images B and C from Schmidt et al. (1998). $\kappa$ is the scaled surface density, $\gamma$ is the shear, $\mu _{\rm tot}$ is the total magnification.
Table 3: Results and confidence limits for g'-band source size, ratio between r'- and g'-band source size and transverse velocity (projected to the lens plane).
Table 4: Probabilites of the image C high magnification event being produced by the source crossing a caustic and of the g' and r'-band region touching a caustic. The table shows the obtained values for the probability both using and not using the Gil-Merino et al. (2005) velocity prior.
