fhxyvel --> fhxvel
frxyvel --> frxvel
What does the f prefix indicate, anyway? These fields are not in the API docs.
I think it would be helpful to have a comment here.
The 'f' prefix comes from edf_data.h which is distributed with the EDF Access API. I guess there it indicates that these values are floats in the original data.
I found it in the documentation after the fact. The f is for "fast". So, "fast gaze x velocity". Exactly how that is different from regular "gaze x velocity" isn't explained.
Anyway, you can close this if you already modified those two strings or let me know if you want me to make a pull request.
