ROSETTA-ORBITER 67P OSINAC 2: Uncalibrated Comet Images from 2016

NASA's Rosetta spacecraft acquired uncalibrated image data of comet 67P/Churyumov-Gerasimenko using the OSIRIS Narrow Angle Camera. The data covers a specific period from February 9 to March 8, 2016, during the mission's first extension phase. This version 3.0 dataset includes updates from external peer reviews, improved documentation, and corrections to data quality handling.

Use Cases

• Process and calibrate raw image data based on the documented DN units and ancillary files.
• Study comet 67P's surface evolution and activity based on the time-series of narrow-angle images.
• Assess image quality and instrument performance based on the included quality maps and header keywords.
• Compare cometary features across different mission phases based on the specified EXT1 period.

Strengths

• Data is from a defined mission phase (ROSETTA EXTENSION 1) covering a specific 28-day period in 2016.
• Version 3.0 includes documented corrections from 2018 external peer reviews and updated ancillary files.
• Dataset includes a user guide with FAQ and image quality sections, and specific handling for images with missing packets.

Limitations

• Data is uncalibrated (CODMAC level 2), 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.
