ROSETTA-ORBITER 67P OSIWAC: Calibrated Comet Images from Extension 3

NASA's Rosetta spacecraft OSIRIS Wide Angle Camera captured radiometric calibrated image data of comet 67P/Churyumov-Gerasimenko. The dataset covers the period from September 2 to September 26, 2016, and contains images calibrated in units of W/m^2/sr/nm. This version 3.0 includes corrections from external reviews and improvements to calibration and documentation.

Use Cases

• Analyzing comet surface brightness and albedo based on radiometric calibration
• Studying temporal changes in comet activity during the September 2016 observation period
• Validating and improving image processing algorithms for spacecraft cameras based on documented calibration improvements
• Comparing comet 67P features with other celestial bodies using calibrated spectral data

Strengths

• Data is radiometric calibrated to physical units (W/m^2/sr/nm)
• Version 3.0 includes corrections from July and October 2018 external peer reviews
• Documentation includes a user guide with FAQ and image quality sections

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
