rfa8011eb r2f0c07d 43 43 44 44 To provide easy access to the orientation of the elliptical cylinder, we define the axis of the cylinder using two 45 angles |theta|, |phi| and |bigpsi| . As for the case of the cylinder, the angles |theta| and |phi| are defined on46 Figure 2 of CylinderModel.The angle |bigpsi| is the rotational angle around its own long_c axis against the *q* plane.45 angles |theta|, |phi| and |bigpsi| (see :ref:`cylinder orientation <cylinder-angle-definition>`). 46 The angle |bigpsi| is the rotational angle around its own long_c axis against the *q* plane. 47 47 For example, |bigpsi| = 0 when the *r_minor* axis is parallel to the *x*\ -axis of the detector. 48 48 49 49 All angle parameters are valid and given only for 2D calculation; ie, an oriented system. 50 50 51 .. figure:: img/elliptical_cylinder_ geometry_2d.jpg51 .. figure:: img/elliptical_cylinder_angle_definition.jpg 52 52 53 53 Definition of angles for 2D 54 54 55 .. figure:: img/c ore_shell_bicelle_fig2.jpg55 .. figure:: img/cylinder_angle_projection.jpg 56 56 57 57 Examples of the angles for oriented elliptical cylinders against the detector plane. … … 60 60 and length values, and used as the effective radius for *S(Q)* when *P(Q)* \* *S(Q)* is applied. 61 61 62 63 .. figure:: img/elliptical_cylinder_comparison_1d.jpg64 65 1D plot using the default values (w/1000 data point).66 62 67 63 Validation
