The PEACE data available via the CSDS is at present (January 2002) all marked as "Not Validated" (see caveats).

You are advised that "Not Validated" data is potentially misleading and we recommend that it should not be used for any kinds of study, including preliminary investigations

See a discussion of issues associated with production of accurate PEACE moments see calibration and spacecraft potential pages

See the CSDS Users Guide for further information, including regarding validation of data.

The PEACE data available via the CSDS consist of
1.    electron density,
2.    electron velocity,
3.    parallel electron temperature,
4.    perpendicular electron temperature and
5.    parallel electron heat flux.

These data are generated at the UK Data Centre using partial moments calculated onboard the spacecraft, based on data collected by the two PEACE sensors on each spacecraft. The parallel and perpendicular quantities are intended to be parallel and perpendicular with respect to the magnetic field vector. They are calculated at the Data Centre using PEACE pressure tensor information together with data from FGM. The FGM team advise that the calibration of the FGM data provided to the Data Center is adequate for spin resolution applications such as this.
