ROSETTA-ORBITER 67P OSIWAC: Calibrated Comet Images from the PRELANDING Phase

Solar stray light corrected, radiometric calibrated, and geometric distortion corrected image data in reflectance units acquired by the OSIRIS Wide Angle Camera on the Rosetta spacecraft. The dataset covers the period from 2014-09-23T10:00:00.000 to 2014-10-24T09:59:59.000, targeting comet 67P/Churyumov-Gerasimenko. This V1.0 dataset is the first version, corrected after an October 2018 external peer review.

Use Cases

• Analyze surface reflectance and albedo variations on the comet based on calibrated reflectance units.
• Study geometric features and morphology using distortion-corrected image data.
• Investigate comet activity and changes during the pre-landing mission phase based on the specified time range.
• Validate or compare with other Rosetta instrument datasets using the peer-reviewed and corrected data.

Strengths

• Data is processed to CODMAC level 4, indicating solar stray light correction, radiometric calibration, and geometric distortion correction.
• Covers a defined one-month period from 2014-09 23 to 2014-10-24 during the critical PRELANDING mission phase.
• Version V1.0 represents a peer-reviewed and corrected dataset following an October 2018 external review.

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.
