**Table 1:** Magnitude offset and time delay measurements in the g band.
Brightness records	Method	Offset^a (mag)	Delay^b (d)
A(season 2)-B(season 3)	$\chi^2$	-0.090 $\pm$ 0.004	417 $\pm$ 2
	D²	-0.092 $\pm$ 0.004	416 $\pm$ 5
AE1-BE1	$\chi^2$	-0.083 $\pm$ 0.006	417 $\pm$ 2
	$\delta ^2$	-	417 $\pm$ 2

^a Magnitude offset between the A and B components, where the sign ``-'' means that A is fainter (see Fig. 6). From $\delta ^2$ we do not measure the shift in magnitude, since $\delta ^2$ is a technique based on autocorrelation and cross-correlation functions. All measurements are 1 $\sigma$ intervals.

^b Delay of the replica variation in B with respect to the variation in A (the A component is leading). All measurements are 1 $\sigma$ intervals.
