Description
From 2014-09-23 to 2014-10-24, this dataset contains radiometric and geometric distortion corrected image data of comet 67P/Churyumov-Gerasimenko, acquired by the OSIRIS Narrow Angle Camera on the Rosetta spacecraft. The data is processed to CODMAC level 4, with solar stray light correction and units in W/m^2/sr/nm. This V1.0 version is the first release from NASA, following an external peer review in October 2018.
Use Cases
Analyzing cometary surface morphology and geology based on the high-resolution, geometrically corrected images.
Studying comet 67P's activity and brightness variations based on the radiometrically calibrated data in physical units.
Validating image processing and correction algorithms for space-based instruments based on the described stray light and distortion corrections.
Conducting temporal studies of the comet's nucleus during the pre-landing mission phase based on the specified one-month observation period.
Strengths
Data is processed to CODMAC level 4, indicating a high standard of calibration and validation.
Images are corrected for solar stray light, geometric distortion, and are radiometrically calibrated.
Covers a defined one-month observation period from 2014-09 23 to 2014-10-24 during a critical mission phase.
Dataset version V1.0 is the result of an external peer review process conducted in October 2018.
Limitations
