6 C- Package flag and logical parameters :
7 C shap_filt_uvStar :: filter applied to u*,v* (before SOLVE_FOR_P)
8 C shap_filt_TrStagg :: if using a Stagger time-step, filter T,S before
9 C computing PhiHyd ;
10 C has no effect if syncr. time step is used
11 C Shap_alwaysExchUV :: always call exch(U,V) nShapUV times
12 C Shap_alwaysExchTr :: always call exch(Tracer) nShapTr times
13 C Note :: those exchanges are part of the filtering itself and
14 C are not dealing with the validity of the output field
15 C in the overlap region.
