4.9.2.1 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.
MONOCULAR Corneal Reflection (CR) Samples
•
"..." if no warning for sample
first character is "I" if sample was interpolated
second character is "C" if CR missing
third character is "R" if CR recovery in progress
BINOCULAR Corneal Reflection (CR) Samples
•
"....." if no warning for sample
first character is "I" if sample was interpolated
second character is "C" if LEFT CR missing
third character is "R" if LEFT CR recovery in progress
fourth character is "C" if RIGHT CR missing
