Fits to the Q1R and Q2R light curve data taken with Gemini (z’), Gemini (r’), and CFHT (Ks) (the corresponding filters are indicated in parentheses). These light curves are plotted as a function of the time in seconds relative to the local closest approach (C/A). The blue dots represent residuals with an arbitrary vertical offset for clarity. Note: the y-axis scale is different in the rightmost panel in each row (dense part of Q1R).
