The SNR is the Signal to Noise Ratio that gives you a measurement of the signal strength. It provides relative power dB as compared to the general noise measurement level.
The Peak Value Index combined with the Size of the Data Array can be use to identify the centering of the peak return in the focus zone (extents of the graph) which gives you some information on the accuracy of the reading.
