See if there was any significant change in the maps created after REFMark U was removed. Extract the data from the Store file.

Here are the Std Devs for the matrix elements of the three LTCS->DSCS maps crated at Argonne on July 2nd: image

This shows that the displacements are consistent on the 10s of micrometers level. A rough estimate of a conservative error upper bound on the transformation of a particular coordinate is about 1 mm. This was determined by propagating the error of a function f(x, c) = c*x in quadrature using c = 1, dc = 2e-5, x = 2e5mm, and dx=1mm. Using a more realistic dx on the order of 10s of micrometers would similarly drop the error estimate down to 10s of micrometers similar to the displacements.
