PDS_VERSION_ID = PDS3 RECORD_TYPE = STREAM OBJECT = TEXT PUBLICATION_DATE = 2019-12-12 NOTE = "Description of contents in the CALIB subdirectory." END_OBJECT = TEXT END 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
