Each participant completed three blocks of one of the four experiments: luminance (P6XX), melanopsin (P5XX), L-M pathway (P7XX), S-(L+M) pathway (P3XX).
Each block produced raw pupillometry data, which were pre-processed by the Pupil Labs software, and the resulting csv files of pupil diameter (and other measures) were renamed as PXXX_SX_pupil_positions.csv. Also required is the annotation file which contains information about which was presented during each trial and the start and end of each trial.
