ROSETTA-ORBITER OSIRIS NAC: Comet 67P Images from Prelanding Phase

From October 24, 2014 to November 21, 2014, the OSIRIS Narrow Angle Camera on the Rosetta spacecraft acquired calibrated image data of comet 67P/Churyumov-Gerasimenko. This dataset contains solar stray-light corrected, in-field stray-light corrected, radiometric calibrated, and geometric distortion corrected images in units of W/m^2/sr/nm. It is a CODMAC level 4 data set produced by NASA and represents the first version (V1.0) following an external peer review.

Use Cases

• Analyzing comet surface brightness and albedo based on radiometric calibrated intensity values.
• Studying comet morphology and topography using geometric distortion corrected images.
• Modeling stray-light effects in spaceborne imagery based on the described correction processes.
• Tracking changes in comet 67P's activity during the specified prelanding mission phase.

Strengths

• Data is corrected for solar stray-light and in-field stray-light, enhancing accuracy.
• Images are radiometric calibrated and geometric distortion corrected, providing standardized physical units.
• Coverage spans a defined period from 2014-10-24T10:00:00.000 to 2014-11-21T23:24:59.000.
• Dataset is versioned (V1.0) and has undergone an external peer review process.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
