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

Uncalibrated image data in DN units acquired by the OSIRIS Narrow Angle Camera on the Rosetta spacecraft. The dataset covers the PRELANDING mission phase from May 7 to June 4, 2014, with the prime target being comet 67P/Churyumov-Gerasimenko. This version 3.0 data is provided by NASA and includes updates from external peer reviews, improved documentation, and enhanced handling of image quality issues.

Use Cases

• Analyze cometary surface features and activity based on uncalibrated narrow-angle images.
• Study temporal changes on comet 67P during the prelanding approach phase mentioned in the description.
• Develop or test image calibration pipelines for OSIRIS NAC data using the provided DN units.
• Assess image data quality using the documented shutter backtravel and readout issues.

Strengths

• Covers a defined 28-day observation period from 2014-05 07 to 2014-06-04.
• Version 3.0 includes corrections from 2018 external peer reviews and updated documentation.
• Includes specific ancillary files like a bandpass filter document and an updated science user guide.

Limitations

• Data is uncalibrated (in DN units), requiring significant preprocessing for scientific analysis.
• Column-level documentation and sample data are unavailable, making field semantics unclear before download.
• The dataset's total size and number of images are unknown, limiting suitability assessment.
