ROSETTA-ORBITER 67P OSIWAC: Calibrated Comet 67P Images from Prelanding Phase

OSIRIS Wide Angle Camera images of comet 67P/Churyumov-Gerasimenko, radiometrically calibrated and geometrically corrected to units of W/m^2/sr/nm. NASA produced this CODMAC level 4 dataset covering the prelanding mission phase from September 23 to October 24, 2014. Version 2.0 incorporates corrections from a 2018 peer review, updated documentation, and improved handling of image quality issues.

Use Cases

• Analyze comet surface albedo and reflectance properties based on radiometrically calibrated image data.
• Study temporal changes in comet 67P's activity and morphology during the prelanding phase.
• Validate or develop geometric correction models for spacecraft imagery using the distortion-corrected data.
• Assess image quality and instrument performance using the documented shutter and readout issue maps.

Strengths

• Data is at CODMAC level 4, indicating radiometric calibration and geometric correction have been applied.
• Coverage is for a defined prelanding mission phase from 2014-09-23 to 2014-10-24.
• Version 2.0 includes updates from an external peer review and enhanced documentation on data quality.

Limitations

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