What are the values in 'Blink' stands for?

[Hey000]

To processed 'blink' ROI of a video, I used an ROI of which the size is around 66x66. As a result, I got values around 1e+05. But if I use pupil ROI, the result I got in 'pupil area' is around 4000 plus. The total size of the ROI is around 4000 plus so I wonder how the 1e+05 values was calculated for blink? May I know what the value shown in 'blink' stands for?

By the way, I used the python version.

Thanks!
