Built in distance calculations?

[pSYeNCe]

I was under the impression that there was no built in way to get distance from the Axis camera. After many hours of searching, I finally ran across this whitepaper on how to do it- however, another team member told me that the distance value is already in the program. If it is there, where is it? I've unbundled the Tracking Data and Target Info clusters to no avail. It would save a lot of time if this value is floating around somewhere...
(We're programming in LabVIEW; I guess it's irrelevant to put that here since this is the LabVIEW subforum, but you never know )
