Weblab supports a heterogenious distribution of cone angles. In this case the final spectrum is a superposition of motional averaged spectra calculated for several cone angles and weighted with the probability given by the distribution function.  Possible distributions are:

</table>
</div>
<p>

From the cone menu you supply &theta;<sub>0</sub> as the center of the distribution as well as the full width 2&sigma;. All values are entered in degree. The use of these formulas should be restricted to small values of &sigma;.

When pressing <i>View</i>, weblab shows a sketch of the distribution function, it will use in its calculation.

It is not possible, to consider a distribution of jump axes or jump rates together with a  distribution of cone angles. If you are interested in one of these, set 'no' for <i>cone angle distribution</i>.
