Coordinates of WPILIB field (Pose Estimator)

Technical Programming

Hello,
I am working on a drag and drop program to find what target values to feed our pose estimator for automatic alignment. I set it up using the field’s top left corner as (0, 0). However, looking at the pose estimator, (0, 0) seems to not be at the corner of the field, but somewhere outside of the field. Below is an image of what I am talking about:

As you can see, they include area outside of the field for whatever reason. Does anyone know the offset from (0, 0) to the top left corner of the field? How wide is the image (including the part outside the field) in meters?

If you just want to find poses for alignment, you can right-click any spot on the Glass Field2d widget and it gives you the pose information.
