Table 4: Time delay results for the D²_4,2 dispersion estimate applied to the RES photometry data. A 5th order polynomial was used to model additional variability in the quasar light curves. Estimated errors are 1 $\sigma$ limits.
Statistic $\delta$ Time delay (days)

D²_4,2 1 411.4 $\pm$ 2.3

D²_4,2 2 411.8 $\pm$ 1.8

D²_4,2 3 411.8 $\pm$ 1.8

D²_4,2 4 411.8 $\pm$ 1.7
