Is there a way of accessing camera tracking data on the CV1?

Sorry if this has been asked before. I searched, but didn't quite find the answer I needed.

Okay, so, I made a decal that covers the entire front of my Rift, and the material is definitely translucent enough that at least *some* of the constellation IR is getting through, as I'm still being tracked with it on.

I did, however, notice myself getting a little dizzy in an app I don't normally notice any problems with (I don't remember which, now), but didn't really see any visible problems.

I took the decal back off, and I *think* the problems went away (if they were even there to begin with).

I can test whether the camera can still see the front constellation LEDs through the decal by just putting my hands in front of the front of the Rift. Hands in front: no positional tracking (rotational-only). No hands in front, even with the decal: positional/rotational tracking.

Anyway, I'd like to find some way of quantifying tracking data for testing. Brightness of the constellation LEDs, whether the camera is losing tracking on any of them (or the lower brightness is causing dropped tracking frames), etc.

Any advice?
