ROSETTA-ORBITER 67P OSIWAC: Calibrated Comet Images from 2014

Radiometric calibrated image data from the OSIRIS Wide Angle Camera on the Rosetta spacecraft, measured in W/m^2/sr/nm. The dataset covers the PRELANDING mission phase from September 23 to October 24, 2014, with the prime target being comet 67P/Churyumov-Gerasimenko. This version 3.0 data set, produced by the National Aeronautics and Space Administration, includes corrections from peer reviews, updated documentation, and improved handling of image quality issues.

Use Cases

• Analyze cometary surface morphology and features based on calibrated wide-angle camera images.
• Study temporal changes in comet 67P's activity during the pre-landing phase.
• Validate and improve radiometric calibration models for space-based instruments.
• Assess image data quality using the provided quality maps and documentation.

Strengths

• Data is radiometrically calibrated to physical units (W/m^2/sr/nm).
• Version 3.0 includes corrections from external peer reviews conducted in 2018.
• Documentation includes a user guide with FAQ and data quality sections, and a bandpass filter document.

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.
