Now, we plot all of that data and now what we can say is, "yes, different symbols for used it is the same data [as] before" and now it's very easy to say, "here was scan 1, trial 1, scan 1, trial 2" and we can look at how do those points trend over the set, in this case, it was repeated studies of the same physical phantom, a king of hardware, and here we can see a big difference between the expected difference and the measurements that were made.  And so here's our plus and minus a tenth of a millimeter.  And we see that basically nearly all of those points lie within a tenth of a millimeter of the expected value.
