ROSETTA-ORBITER 67P OSIWAC: Comet 67P Calibrated Images, September 2014

Radiometric calibrated and geometric distortion corrected image data in W/m^2/sr/nm, acquired by the OSIRIS Wide Angle Camera on the Rosetta spacecraft. The dataset covers the period from 2014-09-02T10:00:00.000 to 2014-09-23T09:59:59.000, targeting comet 67P/Churyumov-Gerasimenko. This version V2.0 data set, provided by the National Aeronautics and Space Administration, includes updates from an external peer review and improved handling of image quality issues.

Use Cases

• Analyzing cometary surface morphology and features based on calibrated wide-angle images.
• Studying temporal changes in comet 67P's activity during the pre-landing mission phase.
• Validating and comparing image processing algorithms using radiometrically calibrated data.
• Assessing image data quality using the documented shutter backtravel and readout issue maps.

Strengths

• Data is radiometrically calibrated to physical units (W/m^2/sr/nm).
• Geometric distortion has been corrected and images are resampled.
• Version V2.0 incorporates corrections from an October 2018 external peer review.
• 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.
