ROSETTA-ORBITER 67P OSIWAC: Comet 67P Calibrated Images from 2016

Radiometric calibrated image data in W/m^2/sr/nm acquired by the OSIRIS Wide Angle Camera on the Rosetta spacecraft during the ROSETTA EXTENSION 3 mission phase. The dataset covers the period from 2016-07 26 to 2016-08-09, with the prime target being comet 67P/Churyumov-Gerasimenko. This version V3.0 data set was produced by the National Aeronautics and Space Administration and includes corrections and documentation updates from 2018 peer reviews.

Use Cases

• Analyzing comet surface morphology and activity based on calibrated wide-angle images.
• Validating radiometric calibration models for spacecraft instruments based on the documented calibration improvements.
• Studying temporal changes in comet 67P's coma and nucleus during the specified two-week period in 2016.
• Assessing image data quality for scientific analysis based on the included quality maps and user guide.

Strengths

• Data is radiometrically calibrated to physical units (W/m^2/sr/nm), enabling quantitative scientific analysis.
• Version V3.0 incorporates corrections from external peer reviews in 2018 and includes updated documentation on data quality and bandpass filters.
• Specific improvements were made to the handling of images with missing packets and the calibration of ballistic mode images.

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.
• The dataset's temporal coverage is limited to a specific two-week period in 2016.
