ROSETTA-ORBITER 67P OSIWAC: Radiometric Images of Comet 67P, 2014

OSIRIS Wide Angle Camera images of comet 67P/Churyumov-Gerasimenko, radiometrically calibrated in W/m^2/sr/nm. The dataset covers the prelanding mission phase from January to May 2014 and is maintained by NASA. Version 3.0 includes corrections from external peer reviews, updated documentation, and improved handling of image quality issues.

Use Cases

• Study comet surface morphology and activity based on calibrated image data.
• Perform photometric analysis of the comet nucleus based on radiometric calibration.
• Assess image data quality for scientific publication based on documented quality maps and updates.
• Compare cometary features over time during the prelanding mission phase.

Strengths

• Data is radiometrically calibrated to physical units (W/m^2/sr/nm).
• Dataset version 3.0 incorporates corrections from 2018 external peer reviews.
• Includes updated documentation on bandpass filters and a user guide with an FAQ section.
• Improved handling of images with missing packets and inclusion of FITs files.

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.
