ROSETTA-ORBITER OSINAC: Comet 67P Reflectance Images from July-August 2016

OSIRIS Narrow Angle Camera images of comet 67P/Churyumov-Gerasimenko, corrected for stray light and geometry and calibrated to reflectance units. The dataset covers a specific two-week period from July 26 to August 9, 2016, during the Rosetta mission's third extension phase. This V1.0 version was produced by NASA following an external peer review in October 2018.

Use Cases

• Analyzing comet surface albedo and reflectance properties based on the calibrated image data.
• Training computer vision models for feature detection on comet surfaces using the geometric distortion corrected images.
• Studying temporal changes on the comet's nucleus during the specified two-week observation period.
• Validating photometric models for solar system bodies using the stray light corrected and radiometric calibrated data.

Strengths

• Data is processed to CODMAC level 4, indicating it is calibrated and corrected for scientific use.
• Images are corrected for solar stray light, radiometric calibration, and geometric distortion.
• Covers a defined 14-day period from 2016-07-26 to 2016-08-09, providing temporal specificity.
• Dataset version V1.0 indicates a reviewed and corrected release following an external peer review.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
• Data may reflect temporal bias inherent to the specific two-week mission phase.
