Mean values of x and z are calculated for the 5 fiducial points:
xmean -129.426 ; zmean 254.160 ; ymean -43.907 ; yRMS 0.048
An x, z translation then maps the mean position to the nominal mean
and allows measured and nominal fiducial points to be compared.
Rmeas is distance from mean to the fiducial point and can be compared with nominal Rnom.
