ROSETTA-ORBITER 67P OSINAC: Calibrated Images of Comet 67P

Radiometric calibrated and geometric distortion corrected image data acquired by the OSIRIS Narrow Angle Camera on the Rosetta spacecraft. The dataset covers observations of comet 67P/Churyumov-Gerasimenko from September 2 to September 26, 2016. This version 2.0 dataset was produced by NASA and includes updates to documentation, ancillary files, and image quality handling.

Use Cases

• Analyze comet surface albedo and reflectance based on radiometric calibration in W/m^2/sr/nm.
• Study geometric features and topography of comet 67P based on distortion-corrected images.
• Assess image data quality and instrument performance based on documented shutter backtravel and readout issues.
• Compare comet activity and changes over time during the September 2016 observation period.
• Validate and improve image processing pipelines using the updated ancillary files and bandpass filter documentation.

Strengths

• Data is radiometric calibrated and geometric distortion corrected, indicating processed scientific quality.
• Version 2.0 includes updates from an external peer review and improved handling of images with missing packets.
• Coverage spans a specific 24-day period from 2016-09-02 to 2016-09-26, providing a temporal snapshot.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified as the last metadata update is dated 2026-03-05.
