    6969  The calculation of $Z(q)$ is a double numerical integral that 
    7070  must be carried out with a high density of points to properly capture 
    71   the sharp peaks of the paracrystalline scattering.      
    72   So be warned that the calculation is slow. Fitting of any experimental data  
     71  the sharp peaks of the paracrystalline scattering. 
     72  So be warned that the calculation is slow. Fitting of any experimental data 
    7373  must be resolution smeared for any meaningful fit. This makes a triple integral 
    7474  which may be very slow.

    7676This example dataset is produced using 200 data points, 
    7777*qmin* = 0.001 |Ang^-1|, *qmax* = 0.1 |Ang^-1| and the above default values. 
     
    7979The 2D (Anisotropic model) is based on the reference below where $I(q)$ is 
    8080approximated for 1d scattering. Thus the scattering pattern for 2D may not 
    81 be accurate, particularly at low $q$. For general details of the calculation and angular
