  "x_description": "High time resolution calibrated waveform data sampled in one of 3 frequency bands in the range 0-577 kHz along one axis using either an electric field antenna or a magnetic search coil sensor.  The dataset also includes instrument mode, data quality and the angles required to orient the measurement with respect to the magnetic field and to the GSE coordinate system. ... The Burst Mode (BM) dataset contains the data that has been returned via the main Cluster telemetry system using BM2. The format of the file is to the waveform product returned via the dedicated communication link except that there is an additional paramter providing information on the data sampling and bandwidth relveant for the BM2 link. ... CALIBRATION: ... The procedure used in computing the calibrated Electric Field and Magnetic Field values found in this file can be obtained from the document CAA-EST-CR-WBD (Calibration Report of the WBD Measurements in the Cluster Science Archive). In the same document are decribed the procedures to calculate power spectra and to invert the calibration to obtain raw instrument data. ... Bandwidth   Sample Rate ---------   ------------ 0.1 - 9.5 kHz      27.443 kHz 0.1 - 19 kHz       54.886 kHz 0.7 - 77 kHz      219.544 kHz ... COORDINATE SYSTEM USED: ... One axis measurements made in the Antenna Coordinate System, i.e., if electric field measurement, it will either be Ey or Ez, both of which are in the spin plane of the spacecraft, and if magnetic field measurement, it will either be Bx, along the spin axis, or By, in spin plane. ... The burst mode file has the same format as the standard WBD waveform with the addition of an additional paramter which describes the details of the mode specification. The paramter can take one of ten values as specified below 0 = Duty Cycled 9.5 kHz, 1-in-3, Sample Rate 27.443 kHz 1 = Duty Cycled 9.5 kHz, 1-in-4, Sample Rate 27.443 kHz 2 = Duty Cycled 19 kHz, 1-in-3, Sample Rate 54.886 kHz 3 = Duty Cycled 19 kHz, 1-in-4, Sample Rate 54.886 kHz 4 = Duty Cycled 77 kHz, 1-in-3, Sample Rate 219.544 kHz 5 = Duty Cycled 77 kHz, 1-in-4, Sample Rate 219.544 kHz 6 = Digital Filtered 9.5 kHz, 1-in-3, roll-off at 3.2 kHz, SR 9.148 kHz 7 = Digital Filtered 9.5 kHz, 1-in-3, optimized roll-off at 4.2 kHz, SR 9.148 kHz 8 = Digital Filtered 9.5 kHz, 1-in-4, roll-off at 2.5 kHz, SR 6.861 kHz 9 = Digital Filtered 9.5 kHz, 1-in-4, optimized roll-off at 3.1 kHz, SR 6.861 kHz ...",
