ZCB PSP FIELDS Digital Fields Board, DFB, Search Coil Magnetometer data: The DFB is the low frequency, less than 75 kHz, component of the FIELDS experiment on the Parker Solar Probe spacecraft, see reference [1] below. For a full description of the FIELDS experiment, see reference [2]. For a description of the DFB, see reference [3]. The DFB continuous waveform data consist of time series data from various FIELDS sensors. These data have been filtered by both analog and digital filters [3]. The Level 2 data products contained in this data file have been calibrated for: * 1) DFB in-band gain * 2) DFB analog filter gain and phase response * 3) DFB digital filter phase response * 4) The search coil preamplifier gain and phase response, when applicable Calibrations for the DFB digital filter gain response have not been implemented, but the required convolution kernel is provided in this file. It was decided not to apply the digital filter gain response calibration to these Level 2 data because the application of the calibrations can introduce non-physical power at high frequencies when the non-corrected signal is dominated by noise. This effect should be examined carefully when determining spectral slopes and features at the highest frequencies. Calibrations for the FIELDS voltage sensor preamplifiers have not been implemented as the preamplifier response is flat and equal to one throughout the DFB frequency range. Corrections for plasma sheath impedance gain and antenna effective length have not been applied to the voltage sensor data. These corrections will be applied in the Level 3 DFB data products. Therefore, all voltage sensor quantities when present in these Level 2 data products are expressed by using units of Volts. Likewise, all magnetic field quantities when present in these Level 2 data products are expressed by using units of nanoTelsas. The Level 2 data products contained in this data file are in spacecraft coordinates (e.g. x,y,z) or in sensor coordinates (e.g. dV12, dV34 for voltage measurements and [u,v,w] for the searchcoil magnetometer. The time resolution of the DFB continuous waveform data can vary by multiples of 2^N. During encounter when PSP is within 0.25 AU of the Sun, the DFB continuous waveform data cadence is typically 256 samples/NYsecond [2].

FIELDS Instrument Suite Data Quality Flags FIELDS quality flags: These flags are bitwise variables, meaning that multiple flags can be set simultaneously for a single time by adding flag values. Current flagged values are: * 1: FIELDS Antenna Bias Sweep * 2: PSP Thruster Firing * 4: SCM Calibration * 8: PSP Rotations for MAG Calibration, MAG Rolls * 16: FIELDS MAG Calibration Sequence * 32: SWEAP SPC in Electron Mode * 64: PSP Solar Limb Sensor, SLS, Test * 128: PSP Spacecraft is off Umbra Pointing, Heat Shield not pointed Sunward * 256: High Frequency Noise affecting RFS and TDS Receivers * 512: Antennas driven towards the FIELDS Power Supply Rails A value of zero corresponds to no set flags. Not all flags are relevant to all FIELDS data products, refer to notes in the CDF metadata and on the FIELDS Satellite Operations Center, SOC, website for information on how the various flags impact FIELDS data. For more information on the quality flags describing high frequency noise and antennas driven to the rails, see release notes for PSP/FIELDS releases 8 and 9. Additional flagged items may be added in the future. PT0.003413S flag I10 0 1023 4294967295 Scalar InstrumentMode
