Localization accuracy.

Abs. dev.	β = 0	β = 1	β = 2	β = 3	Uniform
Pixels	1.96 ± 0.08	1.69 ± 0.11	1.52 ± 0.14	1.41 ± 0.15	3.40
Degrees	0.102 ± 0.004	0.088 ± 0.006	0.079 ± 0.007	0.074 ± 0.008	0.180

Average absolute deviation (±s.e. across subjects) of correct localization responses relative to the target center. Data is given both in pixel units as well as degrees of visual angle. For reference, the absolute deviation assuming a uniform distribution within the acceptance region is also given.
