pyrfu.pyrf.vht module#

pyrfu.pyrf.vht.vht(e, b, no_ez: bool = False)[source]#

Estimate velocity of the De Hoffman-Teller frame from the velocity estimate the electric field eht=-vht x b

Parameters:

  • e (xarray.DataArray) – Time series of the electric field.

  • b (xarray.DataArray) – Time series of the magnetic field.

  • no_ez (boolean, Optional) – If True assumed no Ez. Default is False.

Returns:

  • vht (numpy.ndarray) – De Hoffman Teller frame velocity [km/s].

  • vht (xarray.DataArray) – Time series of the electric field in the De Hoffman frame.

  • dv_ht (numpy.ndarray) – Error of De Hoffman Teller frame.
