******************
Coordinates Shifts
******************

There are many places in the various output results of OP where the words SHIFT or COORDINATE SHIFT will appear. In each case the word SHIFT implies from one value to another value. Typically, the "from" value is the output of the prior adjustment, and the "to" value is the output of the current adjustment. If the user is following the sequential adjustment process outlined in Section 12, the coordinate shifts reported in different parts of the output will differ accordingly.

In general, there are 6 major steps in OP where one can expect to see the words "shift" or "coordinate shift:"

1. Session Processing Results
2. Preliminary Adjustment
3. Horizontal Free Adjustment
4. Horizontal Constrained Adjustment
5. Vertical Free Adjustment
6. Vertical Constrained Adjustment
