Table 6

Confidence intervals for data obtained with Keck telescope (Murphy et al. 2003; King et al. 2012). Comparison with single quasar obtained with the VLT by Srianand (2013, priv. comm.).

cosθ	n	Reported interval	Confidence interval	β for α = 0.05
(1)	(2)	(3)	(4)	(5)

0.248	2	(−0.37,0.77)	(−27.83,25.55)	0.95
0.330	5	(−1.94,0.46)	(−3.97,1.15)	0.93
0.266	7	(−0.68,0.15)	(−3.28,0.49)	0.93
5.047 × 10^-2	13	(−5.87 × 10^-2,0.62)	(−1.21,6.61 × 10^-3)	0.89

Notes. Comparison with single data obtained with the VLT by Srianand (2013, priv. comm). Data sets are selected according to angular position. Columns:

⁽¹⁾

cosθ from data obtained from the VLT;

⁽²⁾

number of data reported by Keck telescope inside the interval;

⁽³⁾

single value reported from the VLT in units of 10^-5;

⁽⁴⁾

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

⁽⁵⁾

type II error probability.
