RtSigmaUnits {OPI}

Response times to white-on-white Goldmann Size III targets for 12 subjects in sigma units

Description

Response times to white-on-white Goldmann Size III targets for 12 subjects. The second column is the distance of the stimuli from measured threshold in 'sigma' units. The threshold was determined by post-hoc fit of a cummulative gaussian FoS curve to the data for each location and subject. Sigma is the standard deviation of the fitted FoS.
