ROSETTA-ORBITER 67P OSIWAC: Calibrated Comet Images from Pre-Landing Phase

From July 2 to August 1, 2014, this dataset contains radiometrically calibrated and geometrically corrected image data in W/m^2/sr/nm, acquired by the OSIRIS Wide Angle Camera on the Rosetta spacecraft. The data targets comet 67P/Churyumov-Gerasimenko and is a CODMAC level 4 product from NASA, with version V2.0 incorporating updates from an external peer review.

Use Cases

• Analyze comet surface morphology and features based on calibrated wide-angle images.
• Study temporal changes in comet activity during the pre-landing phase.
• Validate or improve photometric models using radiometrically calibrated data.
• Assess image quality and instrument performance using documented shutter and readout issue maps.

Strengths

• Data is radiometrically calibrated to physical units (W/m^2/sr/nm) and geometrically corrected.
• Covers a defined one-month observation period from 2014-07 02 to 2014-08-01.
• Version V2.0 includes updates from an October 2018 external peer review and improved handling of images with missing packets.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
