ROSETTA-ORBITER 67P OSIWAC: Calibrated Comet Images from Pre-Landing Phase

From 2014-10-24 to 2014-11-21, the Rosetta spacecraft's OSIRIS Wide Angle Camera acquired radiometrically calibrated image data of comet 67P/Churyumov-Gerasimenko. This CODMAC level 3 dataset, version 3.0, is provided by the National Aeronautics and Space Administration and supersedes previous deliveries with updated documentation and quality improvements.

Use Cases

• Analyzing comet surface morphology and features based on calibrated wide-angle camera imagery.
• Studying cometary activity and outgassing patterns over the pre-landing mission phase.
• Validating and improving radiometric calibration models for space-based instruments.
• Conducting temporal analysis of comet 67P's appearance during the specified observation period.

Strengths

• Data is radiometrically calibrated to physical units (W/m^2/sr/nm).
• Version 3.0 includes corrections from external peer reviews and improved handling of image artifacts.
• Coverage is for a defined 28-day period during a critical mission phase.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
