ROSETTA-ORBITER OSIWAC: Calibrated Spacecraft Imagery from 2008 Cruise Phase

NASA's ROSETTA-ORBITER CHECKOUT OSIWAC 3 CR4A RDR V2.0 dataset contains radiometrically calibrated image data from the OSIRIS Wide Angle Camera on the Rosetta spacecraft. The data covers the CRUISE 4-1 mission phase from January 28 to August 3, 2008, with a prime objective of instrument commissioning and calibration. This version 2.0 dataset was reprocessed following an external peer review in October 2018.

Use Cases

• Calibrating radiometric models for spacecraft cameras based on the calibrated W/m^2/sr/nm data.
• Analyzing instrument performance during the commissioning phase mentioned in the description.
• Studying serendipitous astronomical targets observed during the cruise phase.
• Comparing data processing pipelines using the reprocessed V2.0 delivery.

Strengths

• Data is radiometrically calibrated to physical units (W/m^2/sr/nm).
• Covers a defined 6-month mission phase from 2008-01 28 to 2008-08-03.
• Reprocessed for quality following an October 2018 external peer review.
• Produced by the authoritative source NASA.

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.
• The description notes no identifiable prime target, suggesting observational data may be opportunistic.
