pyrfu.pyrf.new_xyz module#

pyrfu.pyrf.new_xyz.new_xyz(inp, trans_mat)[source]#

Transform the input field to the new frame.

Parameters:

  • inp (xarray.DataArray) – Time series of the input field in the original coordinate system.

  • trans_mat (array_like) – Transformation matrix.

Returns:

out – Time series of the input in the new frame.

Return type:

xarray.DataArray

Examples

>>> from pyrfu import mms, pyrf

Time interval

>>> tint = ["2019-09-14T07:54:00.000", "2019-09-14T08:11:00.000"]

Spacecraft indices

>>> mms_id = 1

Load magnetic field and electric field

>>> b_xyz = mms.get_data("B_gse_fgm_srvy_l2", tint, mms_id)
>>> e_xyz = mms.get_data("E_gse_edp_fast_l2", tint, mms_id)

Compute MVA frame

>>> b_lmn, l, mva = pyrf.mva(b_xyz)

Move electric field to the MVA frame

>>> e_lmn = pyrf.new_xyz(e_xyz, mva)
