    Starts the Fourier calculation. 
 
    The optional parameters enable you to apply a convolution with a 
-   triaxial Gaussian resolution function. The sigma and the directions
-   for the three half axes of the ellipsoid are independent. The
-   directions <h>, <k>, <l> can be omitted. In this case the directions 
-   default to the abscissa, ordinate and top axis of the Fourier 
-   calculation.

+   The sigma's are in units of reciprocal Angstrom, keep in mind that
+   DISCUS uses the definition a* = 1/a instead of a* = 2pi/a.
