[docs]def feeps_correct_energies(feeps_alle):
r"""Modifies the energy table in FEEPS spectra (intensity, count_rate,
counts) using the function: mms_feeps_energy_table (which is s/c, sensor
head and sensor ID dependent)
Parameters
----------
feeps_alle : xarray.Dataset
Dataset containing the energy spectrum of the available eyes of the
Fly's Eye Energetic Particle Spectrometer (FEEPS).
Returns
-------
out : xarray.Dataset
Dataset containing the energy spectrum of the available eyes of the
Fly's Eye Energetic Particle Spectrometer (FEEPS) with corrected
energy table.
