ROSETTA-ORBITER 67P OSINAC 4: Calibrated Comet 67P Images from August 2014

NASA's CODMAC level 4 dataset contains solar and in-field stray-light corrected, radiometrically and geometrically calibrated image data from the OSIRIS Narrow Angle Camera on the Rosetta spacecraft. The data, measured in W/m^2/sr/nm, targets comet 67P/Churyumov-Gerasimenko and covers the period from 2014-08-01T10:00:00.000 to 2014-09-02T09:59:59.000 during the PRELANDING mission phase. This V1.0 version is the first release following a 2019 external peer review.

Use Cases

• Analyze comet surface morphology and albedo variations based on calibrated radiance values.
• Study temporal changes in comet activity during the pre-landing phase based on the month-long observation period.
• Validate or develop photometric models for comet surfaces based on stray-light corrected imagery.
• Perform comparative analysis with other Rosetta instrument datasets based on the specific comet 67P target.

Strengths

• Data has undergone multiple calibration steps including stray-light correction, radiometric calibration, and geometric distortion correction.
• Covers a defined one-month observation period from August to September 2014.
• Produced by NASA and peer-reviewed, with version V1.0 released after external review in 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 for large-scale processing.
