471    C These are input arrays (of integers) that contain the *absolute*
472    C computational index of an open-boundary (OB) point.
473    C A zero (0) element means there is no corresponding OB in that column/row.

475    C For a northern/southern OB, the OB V point is to the south/north.
476    C For an eastern/western OB, the OB U point is to the west/east.
477    C eg.

479    C          T( 3 ,34) is a an OB point
480    C          U(3:4,34) is a an OB point

485    C          U(3:4,1) is a an OB point
486    C          V( 4 ,2) is a an OB point
487    C
488    C For convenience, negative values for Jnorth/Ieast refer to
489    C points relative to the Northern/Eastern edges of the model
490    C eg. OB_Jnorth(3)=-1  means that the point (3,Ny-1) is a northern O-B.
