ROSETTA-ORBITER 67P OSINAC: Calibrated Comet Images from 2014

OSIRIS Narrow Angle Camera images of comet 67P/Churyumov-Gerasimenko, radiometrically calibrated in W/m^2/sr/nm. This version 3.0 dataset from NASA covers the prelanding mission phase from May 7 to June 4, 2014. It supersedes previous versions with corrections from 2018 peer reviews, updated documentation, and improved handling of image quality issues.

Use Cases

• Analyzing comet surface morphology and features based on calibrated narrow-angle images.
• Studying temporal changes in comet activity during the prelanding approach phase mentioned in the description.
• Validating radiometric calibration techniques for space-based camera systems.
• Developing image processing algorithms to handle data quality issues like shutter backtravel and missing packets described in the update notes.

Strengths

• Data is radiometrically calibrated to physical units (W/m^2/sr/nm), enabling quantitative analysis.
• Version 3.0 incorporates corrections from external peer reviews conducted in July and October 2018.
• Includes specific documentation on bandpass filters and an updated user guide with FAQ and data quality sections.
• Covers a defined temporal range from 2014-05-07T12:48:00.000 to 2014-06-04T10:49:59.000.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total file size are unknown, which may limit suitability assessment.
• Data may reflect temporal bias inherent to the specific 2014 prelanding mission phase.
