ROSETTA-ORBITER OSIWAC 4: Calibrated Reflectance Images from Cruise Phase

ROSETTA-ORBITER CHECKOUT OSIWAC 4 CR4A RDR-REFLECT V1.0 is a CODMAC level 4 dataset containing radiometric calibrated and geometric distortion corrected image data in reflectance units. It was acquired by the OSIRIS Wide Angle Camera on the Rosetta spacecraft during the CRUISE 4-1 mission phase from 2008-01-28 to 2008-08-03. The prime objective was commissioning and calibration, with several targets of opportunity observed.

Use Cases

• Validate radiometric calibration algorithms based on the reflectance unit normalization.
• Analyze geometric distortion correction methods based on the resampled image data.
• Study instrument performance during commissioning based on the cruise phase observations.
• Identify targets of opportunity in space imagery based on the unspecified celestial objects.

Strengths

• Data is radiometric calibrated and geometric distortion corrected.
• Specific temporal coverage from 2008-01-28T00:00:00.000 to 2008-08-03T23:59:59.000.
• CODMAC level 4 classification indicates processed, validated data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description notes none of the observed targets of opportunity are identifiable as a prime target.
