C Use [1-d_yy^n)(1-d_xx^n] instead of [1-d_xx^n-d_yy^n] |
| 14 |
C This changes the spectral response function dramatically. |

C You need to do some analysis before changing this option. ;^) |

C This invokes the older code which produces the same numbers |
| 19 |
C and might even be faster because it does not do multiple |
| 20 |
C exchanges within the filter. However, this requires the |
| 21 |
C overlap to be sufficiently wide and also does not work |
| 22 |
C for arbitrarily arranged tiles (ie. as in cubed-sphere). |

C *DO NOT USE THIS OPTION UNLESS YOU REALLY WANT TO* :-( |
