ROSETTA-ORBITER 67P OSINAC: Comet 67P Reflectance Images from Prelanding Phase

Solar stray-light corrected, radiometrically calibrated image data in reflectance units acquired by the OSIRIS Narrow Angle Camera on the Rosetta spacecraft. The dataset covers the period from 2014-01-20 to 2014-05-07, targeting comet 67P/Churyumov-Gerasimenko. This version V1.0 is the first version of this dataset, corrected after a 2019 external peer review.

Use Cases

• Analyzing comet surface features and morphology based on calibrated reflectance images.
• Training computer vision models for automated feature detection on comet surfaces.
• Studying temporal changes on the comet's nucleus during the prelanding approach phase.
• Validating photometric models using the stray-light corrected and normalized reflectance data.

Strengths

• Data is processed to CODMAC level 4, indicating radiometric calibration and geometric correction.
• Images are corrected for solar and in-field stray light, enhancing scientific utility.
• Covers a defined prelanding mission phase from January to May 2014.
• Dataset versioning indicates peer-reviewed corrections (V1.0 after September 2019 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.
• Data may reflect temporal bias inherent to the specific Rosetta mission phase.
