pyrfu.mms.make_model_kappa module

pyrfu.mms.make_model_kappa.make_model_kappa(vdf, n_s, v_xyz_s, t_s, kappa: float = 7.0)

Make a general isottropic kappa distribution function based on particle moment data in the same format as vdf.

Parameters:

• vdf (xarray.Dataset) – Particle distribution (skymap).

• n_s (xarray.DataArray) – Time series of the number density.

• v_xyz_s (xarray.DataArray) – Time series of the bulk velocity.

• t_s (xarray.DataArray) – Time series of the scalar temperature.

• kappa (float. Optional) – Kappa index, Default is 7.

Returns:

out – Distribution function in the same format as vdf.

Return type:

xarray.Dataset
