ROSETTA-ORBITER 67P OSIWAC: Calibrated Comet Images from 2016

Radiometric calibrated 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 2016-03 08T23:25:00.000 to 2016-04-05T23:24:59.000, targeting comet 67P/Churyumov-Gerasimenko. This version V3.0, delivered by the National Aeronautics and Space Administration, includes corrections from 2018 peer reviews and improved calibration for ballistic mode images.

Use Cases

• Analyze cometary surface morphology and changes based on calibrated wide-angle camera imagery.
• Study comet 67P/Churyumov-Gerasimenko's activity and outgassing patterns during the 2016 mission phase.
• Validate or improve radiometric calibration models for space-based instrumentation.
• Perform photometric analysis of cometary nuclei using data in physical units (W/m^2/sr/nm).

Strengths

• Data is radiometrically calibrated to physical units (W/m^2/sr/nm), enabling quantitative scientific analysis.
• Version V3.0 incorporates corrections from July and October 2018 external peer reviews, suggesting rigorous quality control.
• Documentation includes a user guide with FAQ and image data quality sections, and a bandpass filter document.

Limitations

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