ROSETTA-ORBITER OSIRIS NAC: Uncalibrated Images of Comet 67P, 2014

OSIRIS Narrow Angle Camera images of comet 67P/Churyumov-Gerasimenko, acquired by the Rosetta spacecraft from 2014-06-04 to 2014-07-02. This version 3.0 dataset from NASA incorporates corrections from external reviews and includes updated documentation on data quality and filter characteristics. The uncalibrated data in DN units covers the PRELANDING mission phase.

Use Cases

• Calibrate raw image data based on the documented bandpass filter and data quality information.
• Analyze comet surface morphology and activity during approach based on the time-series of uncalibrated images.
• Develop image processing pipelines for spacecraft data based on the handling of images with missing packets.
• Study temporal changes on the comet nucleus based on the month-long observation period.

Strengths

• Data is version 3.0, incorporating corrections from July and October 2018 external peer reviews.
• Covers a specific temporal range from 2014-06-04T10:50:00.000 to 2014-07-02T08:34:59.000.
• Includes updated documentation on bandpass filters, image data quality, and a FAQ section.

Limitations

• Data is uncalibrated (in DN units), requiring significant processing for scientific analysis.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
