ROSETTA-ORBITER 67P OSIWAC 2: Uncalibrated Comet Images from Prelanding Phase

Uncalibrated image data in DN units acquired by the OSIRIS Wide Angle Camera on the Rosetta spacecraft during the PRELANDING mission phase, covering the period from 2014-07-02T08:35:00.000 to 2014-08-01T09:59:59.000. The prime target is comet 67P/Churyumov-Gerasimenko 1 (1969 R1). This version V3.0 dataset was produced by the National Aeronautics and Space Administration and includes updates from peer reviews, improved documentation, and enhanced data quality handling.

Use Cases

• Analyze surface features and morphology of comet 67P based on uncalibrated image data.
• Study temporal changes in cometary activity during the prelanding phase based on the specified time range.
• Assess image data quality and instrument performance based on documented shutter backtravel and readout issues.
• Perform photometric analysis using the included bandpass filter documentation.

Strengths

• Data covers a defined one-month observation period from July to August 2014.
• Version V3.0 incorporates corrections from external peer reviews and includes updated documentation and ancillary files.
• Specific improvements include added FAQ and data quality sections, an image quality map, and improved handling of missing packets.

Limitations

• Data is uncalibrated (CODMAC level 2), requiring further processing for scientific analysis.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset's scale (rows, file size) is unknown, which may limit suitability assessment.
