Table I
Average foveal data of three subjects based upon the number of measurements (N) of log threshold (ΔI) in log trolands at various times (T) in seconds after reduction in adapting intensity from 3.83 log trolands to 0.83 log troland. To convert the data to log millilamberts, subtract the constant amount 1.02 from each datum.
