4.9.3.1 Samples Recorded in Corneal Reflection Mode
If the data file being processed was recorded using corneal reflection mode, each
sample line has an added 3 (monocular) or 5 (binocular) character fields after
all other fields (including resolution and velocity if enabled). These fields
represent warning messages for that sample relating to the corneal reflection
processing.
