ROSETTA-ORBITER 67P OSIWAC 2: Uncalibrated Comet 67P Images from September 2014

Uncalibrated image data in DN units acquired by the OSIRIS Wide Angle Camera on the Rosetta spacecraft during the PRELANDING mission phase. The data covers the period from 2014-09 02T10:00:00.000 to 2014-09-23T09:59:59.000, with the prime target being comet 67P/Churyumov-Gerasimenko. This version V3.0 dataset from NASA supersedes previous deliveries with updated documentation, ancillary files, and improved handling of image quality issues.

Use Cases

• Analyze comet surface morphology and activity based on uncalibrated image data.
• Study temporal changes on comet 67P during the prelanding phase based on the specified date range.
• Perform image calibration and processing workflows based on the DN unit data and documented quality maps.
• Compare comet features across different filter bands based on the added bandpass filter documentation.

Strengths

• Data covers a specific 21-day observation period in September 2014.
• Version V3.0 includes updates from external peer reviews and improved documentation, such as a section on image data quality.
• Merges two previously separate datasets into one covering the full time period.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is described as uncalibrated, which may require significant preprocessing for scientific analysis.
