42c525bfb4 Alis*0011 C Use [1-d_yy^n)(1-d_xx^n] instead of [1-d_xx^n-d_yy^n]
                0012 C This changes the spectral response function dramatically.
                0013 C You need to do some analysis before changing this option. ;^)
                0014 #define SEQUENTIAL_2D_SHAP
                0015
                0016 C This invokes the older code which produces the same numbers
                0017 C and might even be faster because it does not do multiple
                0018 C exchanges within the filter. However, this requires the
                0019 C overlap to be sufficiently wide and also does not work
                0020 C for arbitrarily arranged tiles (ie. as in cubed-sphere).
                0021 C *DO NOT USE THIS OPTION UNLESS YOU REALLY WANT TO*  :-(

                0025 C Boundary conditions for U,V Shapiro code
                0026 C Horizontal shear is calculated as if the boundaries are no-slip
                0027 C Note: option NO_SLIP_SHAP only used in OLD_SHAPIRO_FILTERS ;
                0028 C   it is replaced by parameter "Shap_noSlip=1." in new S/R.

2d831cbbc6 Jean*0032 C Masking of vorticity in dissipation terms (and Shap-Filt)
                0033 C  can be different from the masking applied for momentum advection;
                0034 C This option allows to use the local S/R: SHAP_FILT_RELVORT3 to
                0035 C compute vorticity, instead of pkg/mom_common S/R: MOM_CALC_RELVORT3
