465    C These are input arrays (of integers) that contain the *absolute*
466    C computational index of an open-boundary (OB) point.
467    C A zero (0) element means there is no corresponding OB in that column/row.
468    C The computational coordinate refers to "tracer" cells.
469    C For a northern/southern OB, the OB V point is to the south/north.
470    C For an eastern/western OB, the OB U point is to the west/east.
471    C eg.

473    C          T( 3 ,34) is a an OB point
474    C          U(3:4,34) is a an OB point

480    C          V( 4 ,2) is a an OB point
481    C
482    C For convenience, negative values for Jnorth/Ieast refer to
483    C points relative to the Northern/Eastern edges of the model
484    C eg. OB_Jnorth(3)=-1  means that the point (3,Ny-1) is a northern O-B.
