Output

This function removes columns related to the non-selected eye and renames columns of the selected eye by removing the L_ or R_ prefix. It also adds a column `Pupil.r`.

If both eyes were recorded from, then this function will correlate the pupil data from both eyes and select only one eye data to keep for further preprocessing and output.
