CSDS Data Rights Statement

The CSDS parameters are subject to certain rules regarding their usage. It is not the intention of the Project nor of the PIs that the parameters should be freely available to the entire world, nor that they should be indiscriminately published without prior approval of the appropriate PI. The main reason for this is to guarantee that the PI should have the right of first publication, and that he or she should be able to control improper or incorrect interpretation of the data.

The following statement was agreed upon by the Cluster PIs on February 7, 1995.

  1. Prime Parameter Data Base (PPDB): these data sets, generated by software implemented and maintained under PI supervision, validated by PIs, will be the principal means for establishing multi-instrument, coordinated data analysis for the Cluster investigator teams. The data consist of spin-averaged parameters from all instruments on all four Cluster spacecraft as defined, on inputs from the PIs, by the CSDS IWG (Implementation Working Group). These data will be accessible to all Cluster Co-Is from CSDS data centres. The access by Co-Is to the PPDB is through agreed procedures between PIs, Co-Is, and the Data Centres. The purpose of the PPDB is to establish and carry out coordinated data analysis within the direct Cluster community only. Neither raw data from the PPDB, nor any data derived from the PPDB can be published without the agreement of the PI responsible for the data. It is the responsibility of the PI of each team to ensure that all Co-Is are aware of their obligations under this agreement and that in the event of violation their privileges may be withdrawn.
  2. Summary Parameter Data Base (SPDB): these data sets, generated by software implemented and maintained under PI supervision, validated by PIs, will be available to the Cluster investigator teams and to a much wider community, on a best efforts basis, for establishing scientific co-operation with other space missions and with ground based investigators. The data consist of one-minute averaged parameters from all instruments from one of the four Cluster spacecraft as defined, on inputs from the PIs, by the CSDS IWG. These data will be accessible and/or distributed from CSDS Data Centres. Access to these data is not restricted; implementation of access and distribution is a responsibility of the Data Centres. The purpose of the SPDB is to establish coordinated data analysis between Cluster teams and a wide and diverse scientific community. All recipients of the data and the summary plots will be informed that neither raw data from the SPDB, nor any data derived from the SPDB can be published without the agreement of the PI responsible for the data.
  3. FGM Processing Support Data Set (FGM-PSDS): this data set, generated by software implemented and maintained under the supervision of the FGM PI and validated by the FGM PI, will be available in the Data Centres for supporting the generation of the PPDB/SPDB of those investigations which require FGM data for these purposes. These data consist of one-second resolution spot values of magnetic field vectors from all four spacecraft. The FGM-PSDS will not be used for purposes other than the generation of other instruments'  PPDB/SPDB, except with the specific agreement of the FGM PI. Data Centres generating the FGM-PSDS will be required to ensure conformance with this agreement.
  4. All Cluster data not covered by the categories above, and not held at the CSDS Data Centres will be accessible from the PIs of the different Cluster investigations, or from their designated Co-Is, through data access procedures which will be agreed between the PI and the recipient of the data (including other Cluster PIs and Co-Is) on a case-by-case basis. The recipient of the data will be responsible to ensure that the data use remains within the framework agreed by the PI providing the data.
