ROSETTA-ORBITER OSIWAC: Calibrated Comet 67P Images from May-June 2014

Solar stray-light corrected, 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 2014 05 07 to 2014 06 04, targeting comet 67P/Churyumov-Gerasimenko. This V1.0 dataset is the first version from the National Aeronautics and Space Administration, corrected after a 2019 external peer review.

Use Cases

• Analyze comet surface brightness and albedo variations based on radiometric calibrated image data.
• Study the evolution of comet 67P's coma and nucleus features during the pre-landing mission phase.
• Validate or train image correction algorithms for stray-light removal using the provided corrected data.
• Perform photometric analysis of cometary activity using the calibrated radiance units (W/m^2/sr/nm).

Strengths

• Data has undergone multiple correction stages: solar stray-light, in-field stray-light, radiometric, and geometric distortion correction.
• Covers a defined pre-landing mission phase from 2014-05-07 to 2014-06-04, providing temporal context.
• Version V1.0 indicates a peer-reviewed, corrected release following an external review in September 2019.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
