kinect TOP - depth map to metres?

For the kinect TOP, is there a table somewhere to figure out what color pixel corresponds to what depth in metres?

rod.

If I remember correctly 1 would be 8.192 meters. The camera will clip depths above 4m currently though. 0 is 0m, but itll clip things below 0.4 meters in near mode. So values of 0 and 1 are undefined.
