ROSETTA-ORBITER 67P: OSIRIS Wide Angle Camera Images of Comet 67P, 2014

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, in reflectance units, was acquired during the PRELANDING mission phase from 2014-01-20 to 2014-05-07, with comet 67P/Churyumov-Gerasimenko as the prime target. This V1.0 version is the first release, corrected after an October 2018 external peer review.

Use Cases

• Analyze comet surface reflectance and albedo based on the radiometric calibrated image data.
• Study the geometric features of comet 67P based on the distortion corrected imagery.
• Model solar illumination and stray light effects on comet observations based on the correction processes mentioned.
• Conduct temporal analysis of comet appearance during the pre-landing phase from January to May 2014.

Strengths

• Data has undergone multiple correction processes: solar stray light correction, radiometric calibration, and geometric distortion correction.
• Covers a defined temporal range from 2014-01 20T10:00:00.000 to 2014-05-07T12:47:59.000.
• Dataset is versioned (V1.0) and has passed an external peer review as noted in the description.

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.
• Data is from a specific mission phase (PRELANDING) and time period, which may limit generalizability.
