Vive Pro Eye: Finding a single eye origin in world space

Howdy. I've just started playing with the SRanipal Unity SDK for the Vive Pro Eye and am trying to understand some of the data I'm getting back. 

 

When I look at the SingleEyeData for the left eye, there's a field for gaze_origin_mm. First off, the comments say that's in Meter Miles, which I don't think is a thing ;) Second, how would I go about converting that to a point in world space?

 

What is the origin which gaze_origin_mm is based around? The documentation for SingleEyeData makes it look like it's the center of the lens in front of that eye. If so, what is the relationship between the center of that lens and something like the main camera?

 

Thanks.
