Missing information

So, now we know that the horizontal resolution is an impressive 70cm, but not so much about the vertical resolution.

Resolving round trip time to a billionth of a second gives a theoretical accuracy of 0.1mm, but when other factors such as the accuracy with which the orbital altitude is known, atmospheric interference, etc are included, the measurement accuracy will almost certainly not be +/- 0.1mm. Its disappointing that the expected error bars on this measurement weren't quoted.
