Notes. Comparison with single data obtained with the Keck telescope (Murphy et al. 2003; King et al. 2012) (group I). Data sets are selected according to angular position. Columns:

⁽¹⁾

cosθ of data from the Keck telescope (group I);

⁽²⁾

number of data reported by the VLT inside the interval;

⁽³⁾

single value reported by Keck in units of 10^-5;

⁽⁴⁾

calculated confidence interval from the VLT data in units of 10^-5;

⁽⁵⁾

type II error probability.
