MAPSview - Data Usage Policy ("Rules-of-the-Road")

The MAPS Key Parameter data files accessible throughout this web site are available to the entire Cassini science community. The data should become available roughly one month after download from the spacecraft. The data available for download from these sites is not to be considered in the public domain until archived in the PDS one year after download from the spacecraft.

It should be clear that the data is being produced quickly in order to facilitate coordinated science and therefore will not have been scrutinized to the same extent as data ready for archiving. Because of this, the data should be considered first look and PI consultation should be undertaken before extensive scientific study.

Until it has been archived in the PDS, the MAPS Key Parameter data will be governed by the MAPS Rules-of-the-Road and by the Cassini Rules-of-the-Road documents. Please read and review these documents before downloading any data.


Rules of the Road Documentation

Cassini/Huygens Mission - MAPS Discipline Working Group (September, 2000)

 MAPS Rules of the Road (PDF)

The Magnetosphere and Plasma Science Discipline Working Group (MAPS) of the Cassini Huygens Mission agrees to the following set of procedures and rules to assure an orderly and efficient analysis and interpretation of the mission's scientific results.

  1. Instrument Principal Investigators (PI), Science Team Leaders (TL) and Interdisciplinary Scientists (IDS) will be designated MAPS PIs. It is the responsibility of MAPS PIs to ensure that the Rules-of-the-Road are observed by their team. MAPS instrument PIs and TLs will be referred to as instrument PIs. The MAPS team is composed of all MAPS PIs, their CoIs, team members and associates (such as students, postdocs, etc.). Each team member must be sponsored by a MAPS PI.
  2. Each instrument PI is responsible for the analysis of data from his/her instrument. The instrument PIs and their CoIs are responsible for the initial analysis, interpretation, and publication of these data.
  3. IDSs are expected, under normal circumstances, to carry out investigations that involve more than one instrument. This may occur either as a result of their proposing such investigation, or their being invited to participate in investigations by other MAPS PIs. When investigations are proposed in an area in which an IDS is known to have an interest, the normal procedure will be to invite him/her to participate.
  4. All instrument PIs are expected to contribute their processed data for MAPS team use. However, these data are to be used for correlative studies only.
  5. When data from an instrument are used in a correlative study, the instrument PI responsible for the data must be informed of their use, and invited at an early time (preferably before the investigation begins) to participate (directly or through designated associates) in the study. The collaborators from the data providing instrument should be invited, through the PI, to be co-authors of any resulting publication or presentation (including abstract of a presentation).
  6. The combined summary plots are made available to MAPS to identify possible scientifically interesting events. These plots are not intended for publication purposes, and may not be published without the specific authorization of the appropriate instrument PI. However, summary plots can be used in oral presentations to demonstrate potential new science. In such cases appropriate credit must be given to the instrument PI.
  7. Each MAPS member entrusted with the summary plots are required to see that they are not distributed beyond the MAPS community without the specific permission of the instrument PIs who contributed data to the summary plot.
  8. Any instrument PI can release data from his/her instrument to anyone, but no data can be released or published without the permission of the appropriate instrument PI.

Cassini/Huygens Rules of the Road

 Cassini/Huygens Rules of the Road (PDF)

Rules of the Road offers guidelines for multi-investigation studies only and it applies equally and fairly to all Cassini/Huygens Teams.

  • Cassini/Huygens Teams are headed by a PSG member (PI, TL, or IDS). Team members are: team lead, official CoIs, NASA/ESA selected Facility Team Members, and their direct associates. Each associate is authenticated by the team lead.
  • Each Cassini/Huygens Team has overall responsibility for its investigation, including the initial analysis, interpretation, and publication of their data. Results from single investigations should be published first as much as possible.
  • All Cassini/Huygens Teams are expected to make available their processed data for Cassini/Huygens team use for multi-investigation studies within a reasonable time (up to 6 months).
  • The combined data sets are made available to all interested Cassini/Huygens Scientists to identify possible scientifically interesting events.
  • The combined data sets may not be published or released without the specific authorization of all contributing Cassini/Huygens Teams.
  • When data from a Cassini/Huygens Team are used in a multi-investigation study:
    • The team lead must be immediately informed of their use.
    • The team must be invited at an early time to participate in the study.
    • The team must be invited to participate in any resulting publication or presentation.
    • First authorship should be fairly divided between the participating teams.
    • Disputes should be resolved at the lowest possible level.
  • The Cassini/Huygens Science Team needs to create a positive atmosphere that strongly discourages misconduct and maximizes science return from the mission.
  • It is the responsibility of all Cassini/Huygens Teams to make sure that all team members and associates are aware of the Rules of the Road and that they abide by them.

These principles where unanimously accepted by the Cassini PSG Executive Session on October 24, 2002.
