- pyrfu.mms.vdf_omni.vdf_omni(vdf, method: str = 'mean')[source]#
Computes omni-directional distribution, without changing the units.
- Parameters:
vdf (xarray.Dataset) –
- Time series of the 3D velocity distribution with :
time : Time samples.
data : 3D velocity distribution.
energy : Energy levels.
phi : Azimuthal angles.
theta : Elevation angle.
method ({"mean", "sum"}, Optional) – Method of computation. Use “sum” for counts and “mean” for everything else. Default is “mean”.
- Returns:
out – Time series of the omnidirectional velocity distribution function.
- Return type:
