The EWO consists of three sets of receivers: EWO-EFD (Electric Field Detector), EWO-WFC/OFA(E) (Wave-Form Capture/Onboard Frequency Analyzer for Electric field), and EWO-WFC/OFA(B) (WFC/OFA for Magnetic field) [Sec.5 of Kasaba et al. (2020a)]. Those receivers observe waveforms and spectra in the frequency range from DC (very low frequency) to 120 kHz for the electric field and from 0.3 Hz to 20 kHz for the magnetic field. The EWO covers the frequency range of various plasma waves in and around the Hermean magnetosphere. The basic design is similar to that of the PWE EWO unit aboard the Arase PWE (Kasahara et al. 2018a; Kasaba et al. 2017).

=== File name convention ===
  * bc_mmo_pwi-efd_l2_**Data mode**-**Date type**_YYYYMMDD_rXX-vYY-ZZ.cdf 
    * **Data mode**: low (L), medium (M), and high (H) modes.
    * **Date type**: E-field (e_spin, e_waveform_pwi, and e_waveform_msm), potential (pot, pot_waveform), and spectrum (spec).
    * Version number:
      * XX: release version
      * YY: major version
      * ZZ: minor version

=== Coordinates for L2 data === 
    * **MMO_SPACECRAFT (PWI_MEF1, PWI_MEF2, PWI_WPT1, and PWI_WPT2) for no despun data**
      * The PWI_MEF1 and PWI_SC frames -- MMO_PWI_MEF1 -- and -- MMO_PWI_SC-- are defined as a fixed offset with respect to the MMO_SPACECRAFT frame as follows:
        *  +Z axis is nominally co-aligned to the +Zsc axis;
        *  +X axis is nominally co-aligned to the +Xsc axis;
        *  +Y axis completes the right hand frame;
        *  The origin of this frame is located at the geometrical center of the detector.
    * **MMO_X_SUN_MEAS (XSM) for despun L2 data**  
      * The MMO Spin Axis Measured frame -- MMO_X_SUN_MEAS -- is a frame used in the science phase reconstructed CK files. This frame represents MM0_SPACECRAFT when Sun Pulse time is recorded (Phase = 0).
        * Data type
          * e_spin: spin-fitted electric field data
          * e_waveform_msm: waveform data
    * **Spin phase**
      * The spin phase is 0 degree when Sun Sensor is toward Sun.
      * +X: +135 degrees, +Y: +225 degrees, -X: +315 degrees, -Y: +45 degrees when the spin phase is 0 degree.
