ROSETTA-ORBITER 67P OSINAC: Solar-Stray-Light Corrected Comet Images, 2014

NASA's Rosetta spacecraft OSIRIS Narrow Angle Camera captured calibrated image data of comet 67P/Churyumov-Gerasimenko from August to September 2014. The dataset contains solar stray light corrected, radiometric calibrated, and geometrically distortion corrected images in units of W/m^2/sr/nm. This version V1.0 is the first release following an external peer review in October 2018.

Use Cases

• Analyzing comet surface morphology and albedo based on calibrated radiance values.
• Studying temporal changes in comet activity during the pre-landing mission phase.
• Validating and developing image correction algorithms for solar stray light removal.
• Comparing geometric features with other Rosetta instrument datasets.

Strengths

• Data is calibrated to physical radiance units (W/m^2/sr/nm), enabling quantitative analysis.
• Images have undergone three specific corrections: solar stray light, radiometric, and geometric distortion.
• Covers a defined one-month observation period from 2014-08-01 to 2014-09-02.
• Dataset version V1.0 indicates a peer-reviewed, stable release.

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 2014 observation window.
