ROSETTA-ORBITER 67P ROSINA 3: Comet 67P Gas Composition Data

ROSETTA-ORBITER 67P ROSINA 3 EXT1 V2.0 contains CODMAC level 3 science data from the DFMS and RTOF sensors on the Rosetta spacecraft. The data was acquired between 2016-01-13 and 2016-04-05 during the Extension phase 1 of the mission to comet 67P/Churyumov–Gerasimenko. Version 2.0 features an enhanced mass scale with 4-digit precision for selected masses, improved offset removal, and the removal of corrupted files.

Use Cases

• Analyzing the temporal evolution of gas composition based on mass spectrometry data.
• Studying comet outgassing activity based on sensor readings from the Rosetta mission's extension phase.
• Calibrating mass spectrometry models based on the enhanced mass scale and offset corrections described.
• Investigating specific molecular species in the comet's coma based on the high-precision mass data.

Strengths

• Data is from the Rosetta mission, a major European Space Agency endeavor with NASA involvement.
• Covers a specific 83-day observation period during the mission's Extension phase 1.
• Version 2.0 includes specific improvements: enhanced mass scale precision and removal of corrupted files.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
