This directory contains calibration data derived both from in-flight
calibrations and data from ground calibrations. The left column refers to
strings contained in the filenames. See document
DOCUMENT/RO-IRFU-LAP-EAICD.PDF for details.

NOTE: Not all data sets contain all types of calibration data products.

_COEFF          Calibration data derived from in-flight calibrations.
                Coefficients which can be used to derive bias-dependent
                current offsets.
_MEAS           Ground calibration version of the _COEFF files, although
                explicitly for every bias.
_IBIAS, _VBIAS  Ground calibrations of bias calibrations, thus mappings from
                set bias and measured bias.
_FINE           Ground calibrations of fine stepping voltages in fine
                sweeping mode.
_NED            Coefficients for deriving NED plasma density data product.
_NEL_I          Coefficients for deriving NEL plasma density data product.
_NEL_V          Coefficients for deriving NEL plasma density data product.



Files (file names) containing the string _FRQ_ are ground frequency
calibrations.

_FRQ_E_         E-Field mode frequency responses.
_FRQ_D_         Density mode frequency responses.

_P1             Indicates sensor/probe 1
_P2             Indicates sensor/probe 2
