1000	!! --> If ocean stress was really received:

1002	!! - transform the received ocean stress vector from the received

1005	!! The received stress are :

1008	!! - oriented along geographical coordinate (if eastward-northward)
1009	!! or along the local grid coordinate (if local grid)
1010	!! - given at U- and V-point, resp. if received on 2 grids
1011	!! or at T-point if received on 1 grid
1012	!! Therefore and if necessary, they are successively
