ROSETTA-ORBITER 67P OSIWAC: Calibrated Comet Images from Rosetta Extension 1

From 2016-02-09 to 2016-03-08, this dataset contains radiometrically calibrated image data of comet 67P/Churyumov-Gerasimenko, acquired by the OSIRIS Wide Angle Camera on the Rosetta spacecraft. The data is provided by the National Aeronautics and Space Administration and represents a processed, version 3.0 release with corrections and documentation updates.

Use Cases

• Analyzing comet surface morphology and albedo variations based on calibrated image data.
• Studying comet 67P's activity and outgassing processes using time-series imagery.
• Validating and improving radiometric calibration models for space-based instruments.
• Conducting photometric studies of the comet nucleus using the provided W/m^2/sr/nm units.

Strengths

• Data is radiometrically calibrated to physical units (W/m^2/sr/nm).
• Version 3.0 includes corrections from external peer reviews and improved calibration for specific image modes.
• Dataset covers a defined mission phase from February to March 2016.

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.
• Description metadata is limited; actual data quality requires manual inspection after download.
