Search and correction coordinate systems differ.

Cause:

The reference coordinate systems of the CD variables used in the correction statement are inconsistent.

Troubleshooting:

Check whether every CD variable in the statement reporting the error has the same reference coordinate system.

Solution:

Change the reference coordinate systems of the CD variables so that every CD variable in one correction statement uses the same reference coordinate system.

Case sharing:

CORR_2D(cd0,cd1)
If the reference coordinate system of cd0 is ref0 and that of cd1 is ref1, running this statement reports error 3498.
If the reference coordinate system of cd1 is also changed to ref0, running this correction statement will not report error 3498.
