ROSETTA-ORBITER OSIWAC: Calibrated Images of Comet 67P, October-November 2014

NASA's CODMAC level 4 dataset contains solar and in-field stray-light corrected, radiometric and geometric distortion calibrated image data from the OSIRIS Wide Angle Camera on the Rosetta spacecraft. The data, in units of W/m^2/sr/nm, were acquired during the PRELANDING mission phase from October 24 to November 21, 2014, with comet 67P/Churyumov-Gerasimenko as the prime target. This V1.0 version is the first release following a September 2019 PSA/PDS external peer review.

Use Cases

• Analyze cometary surface morphology based on calibrated wide-angle camera images.
• Study temporal changes in comet 67P's activity during the pre-landing phase.
• Perform photometric analysis based on radiometric calibrated data in W/m^2/sr/nm.
• Validate geometric correction models for spacecraft imaging instruments.
• Compare cometary features using stray-light corrected image data.

Strengths

• Data is calibrated to CODMAC level 4, indicating processed and corrected scientific data.
• Images are radiometric calibrated with units of W/m^2/sr/nm.
• Coverage spans a defined period from 2014-10-24 to 2014-11-21.
• Dataset has undergone an external peer review (PSA/PDS) in September 2019.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
