ROSETTA-ORBITER 67P OSINAC: Calibrated Comet 67P Images from July-August 2014

Calibrated image data from the OSIRIS Narrow Angle Camera on the Rosetta spacecraft, targeting comet 67P/Churyumov-Gerasimenko. The dataset contains solar and in-field stray-light corrected, radiometric and geometric distortion corrected images in W/m^2/sr/nm, covering the period from 2014-07-02 to 2014-08-01. This V1.0 dataset was produced by the National Aeronautics and Space Administration following a 2019 external peer review.

Use Cases

• Analyze comet surface morphology and albedo based on calibrated radiance values.
• Study temporal changes on the comet nucleus based on images from a defined mission phase.
• Validate or develop image correction algorithms based on the described stray-light and geometric corrections.
• Model comet activity and outgassing based on high-resolution narrow-angle imagery.

Strengths

• Data is calibrated to physical radiance units (W/m^2/sr/nm), enabling quantitative analysis.
• Images are corrected for multiple artifacts: solar stray-light, in-field stray-light, and geometric distortion.
• Covers a defined pre-landing mission phase from July 2 to August 1, 2014, providing temporal context.
• Dataset version (V1.0) indicates a peer-reviewed release following external review in September 2019.

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.
