ROSETTA-ORBITER 67P OSIWAC: Solar Stray Light Corrected Comet Images, 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, measured in W/m^2/sr/nm, covers the period from 2014-01-20 to 2014-05-07, targeting comet 67P/Churyumov-Gerasimenko. This V1.0 version is the first release following an external peer review in October 2018.

Use Cases

• Analyze comet surface morphology and activity based on calibrated, stray-light-corrected images.
• Study temporal changes in comet brightness and features during the prelanding mission phase.
• Validate geometric correction and radiometric calibration models for space instrument data.
• Perform photometric analysis of the comet nucleus using the provided W/m^2/sr/nm units.

Strengths

• Data has undergone multiple corrections for solar stray light, radiometric calibration, and geometric distortion.
• Covers a defined observation period from 2014-01-20T10:00:00.000 to 2014-05-07T12:47:59.000.
• Dataset is a CODMAC level 4 product, indicating a peer-reviewed, calibrated data record.
• Produced by NASA, an authoritative source for space science data.

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 may reflect temporal bias inherent to the specific 2014 prelanding mission phase.
