This CSV file contains the following fields:

- string **participant\_id** - UUID,
- string **participant\_external\_id** - UUID,
- int **participant\_age** - participant's age given at the end of the study; could be undefined if the participant did not provide this info,
- int **participant\_gender** - participant's gender given at the end of the study: 0 - female, 1 - male, 2 - other; could be undefined if the participant did not provide this info,
- string **participant\_display\_gender** - participant's gender given at the end of the study; could be undefined if a participant did not provide this info,
- string **participant\_tags** - tags assigned to a participant (added by the study owner),
- int **participant\_quality\_grade** - participant's grade from 1 to 6 where:
- 1 = very low,
- 2 = low,
- 3 = average,
- 4 = good,
- 5 = very good,
- 6 = perfect;
- int **participant\_quality\_grade\_item** - item's grade from 1 to 6 where:
- 1 = very low,
- 2 = low,
- 3 = average,
- 4 = good,
- 5 = very good,
- 6 = perfect;
- string **item\_id** - UUID,
- string **test\_id** - UUID,
- timestamp **test\_created\_at** - when the participant provided the result,
- int **test\_duration\_ms** - stimuli view time in ms (it may be shorter than defined in settings due to image mapping with clicks),
- int **test\_browser\_width\_px** - participant’s screen width in pixels,
- int **test\_browser\_height\_pv** - participant’s screen height in pixels,
- int **test\_item\_display\_order** - a number indicating the order in which the items were displayed,
- int **exposure\_number** - (only applicable for [Website Mockup](https://support.realeye.io/mockup-studies/?hsLang=en) studies) indicates the time the participant saw an item, i.e., 1 means that the participant saw this item for the first time,
- float **gaze\_x\_percents** - X position of the eyes in percent of the item width (the left edge of the picture is 0%, the right - 100%),
- float **gaze\_y\_percents** - Y position of the eyes in percent of the item width (the top of the picture is 0%, the bottom - 100%),
- int **gaze\_timestamp\_ms** - time in ms since the beginning of the test,
- float **mouse\_x\_percents** - X position of the mouse cursor in percent of the item width (the left edge of the picture is 0%, the right - 100%),
- float **mouse\_y\_percents** - Y position of the mouse cursor in percent of the item height (the top of the picture is 0%, the bottom - 100%); this value includes scroll,
- boolean **mouse\_has\_clicked** - indicating if the participant has clicked at that time; if not clicked then this data is not included,
- string **external\_data\_debug** - any external values assigned to the participant, i.e., external Id from an external survey (if applicable),
- **notes**:
- **notes**:
- RealEye version,
- [fixation filter](https://realeye.user.com/knowledge-base/articles/60/update/63/%7B%%20kb_article_url%2053%20%%7D) settings:
- gazepoint interpolation (Hz) - to improve calculations we interpolate the data to 60 Hz;
- gazepoint interpolation max gap (ms) - we interpolate data if the timestamp gap between two input values is not bigger than this value (50 ms);
- gaze velocity threshold;
- min. fixation duration (Ms);
- max. fixation duration (Ms);
- moving median range (Ms);
- saccade max duration (Ms);
- participantQualityGradeItemMin=X - CSV file can be downloaded filtered by the item quality grade, where X is a value from 1 (very low) to 6 (perfect),
- timestamp of when the file was downloaded.
