Hi, do you have the Kappa Plasma distribution? I see in the electronDistrib that its value is the GlobalMaxwellBoltzmannVolDistrib. Is there a KappaVolDistrib? It is sometimes used at GEO. Thank you!

Hi,
how to set user defined distributions, including kappa, is described in page 6 of Spis-5.2.4/documentation/TechnicalNotes/ESA-SPIS-SCI-D5-SUM-2013-03-001.pdf
An example of user defined distribution is described in page 9 of Spis-5.2.4/documentation/TechnicalNotes/RT-8-17826-SPIS-SCI-VTR-v1.2.pdf, and the template project is located at Spis-5.2.4/data/SCI-projects-19062014/SPIS-SCIENCE-TestSequence1-I.spis5
Simply replace the isotropic tabulated DF by a kappa DF with input parameters.

Thank you! I was able to find it in the DefaultStudy/Simulations/Run1/NumKernel/Input, change the filename, and of course the v and f(v).
