Time series data for Figure 4 of the manuscript. The file contains 110 time series (columns), each is 1 second duration, sampled at 100kHz. Time series 1 to 10 (ie., columns 1 to 10) are measurements of a test patch at 0% luminance. Time series 11 to 20 are measurements of a test patch at 10% luminance. And so on. Unit of measure is mV.
