ROSETTA-ORBITER 67P OSIWAC: Calibrated Comet 67P Images from Rosetta's OSIRIS Camera

NASA's CODMAC level 4 dataset contains solar stray-light corrected, radiometric calibrated, and geometric distortion corrected image data from the OSIRIS Wide Angle Camera on the Rosetta spacecraft. The data covers the period from 2014-08-01 to 2014-09-02, targeting comet 67P/Churyumov-Gerasimenko. This V1.0 version is the first release, corrected after a 2019 external peer review.

Use Cases

• Analyze comet surface morphology based on calibrated, high-resolution imagery.
• Study temporal changes in comet activity during the pre-landing mission phase.
• Validate or develop image processing algorithms for stray-light and radiometric correction.
• Conduct photometric studies of the comet nucleus using data in physical units (W/m^2/sr/nm).

Strengths

• Data is corrected for multiple instrumental effects: solar stray-light, in-field stray-light, radiometric calibration, and geometric distortion.
• Covers a defined one-month observation period from 2014-08-01T10:00:00.000 to 2014-09-02T09:59:59.000.
• Data is provided in physical radiometric units (W/m^2/sr/nm), enabling quantitative analysis.
• Dataset is versioned (V1.0) and has undergone an external peer review process as of September 2019.

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.
• The dataset's specific file formats are not listed in the provided metadata.
