    4343The third orientation distribution, in $\psi$, is about the $c$ axis of the particle. Some experimentation may be required to 
    44 understand the 2d patterns fully. A number of different shapes of distribution are available, as described for polydispersity.

    5253values of Npts and Nsigs, the number of steps used in the integration and the range spanned in number of standard deviations. 
    5354The standard deviation is entered in units of degrees. For a rectangular (uniform) distribution the full width  
    54 should be $\pm\sqrt(3)$ ~ 1.73 standard deviations. 
     55should be $\pm\sqrt(3)$ ~ 1.73 standard deviations (this may be changed soon).

    5657Where appropriate, for best numerical results, keep $a < b < c$ and the $\theta$ distribution narrower than the $\phi$ distribution.
