r9bc4882 reda8b30 73 73 carried out with a high density of points to properly capture the sharp 74 74 peaks of the paracrystalline scattering. 75 So be warned that the calculation is SLOW. Go get some coffee. 76 Fitting of any experimental data must be resolution smeared for any 77 meaningful fit. This makes a triple integral. Very, very slow. 78 Go get lunch! 75 So be warned that the calculation is slow. Fitting of any experimental data 76 must be resolution smeared for any meaningful fit. This makes a triple integral 77 which may be very slow. 79 78 80 79 The 2D (Anisotropic model) is based on the reference below where *I(q)* is 81 80 approximated for 1d scattering. Thus the scattering pattern for 2D may not 82 be accurate. Note that we are not responsible for any incorrectness of the 2D 83 model computation. 81 be accurate particularly at low $q$. For general details of the calculation 82 and angular dispersions for oriented particles see :ref:`orientation` . 83 Note that we are not responsible for any incorrectness of the 84 2D model computation. 84 85 85 86 .. figure:: img/parallelepiped_angle_definition.png
