From page 41...
... Catalogue data, including photometric source catalogues that tabulate brightness measurements taken over time, represent a higher-level product that is generated from the image data. The publication of such catalogues enables, for instance, the derivation of absolute magnitudes, which crucially support the data provided by a midinfrared survey system by enabling the estimation of albedos and improving diameter estimates based on thermal models.
From page 42...
... Finding: The current system for archiving NEO data is not optimized for accessing data and analyzing data in an automated fashion, and there is no consistent NASA policy on archiving NEO survey data. The committee heard from experts on data archiving and was reassured that storage capacity for data will not be a problem in the future, given regular and reasonable upgrades to storage systems.
From page 43...
... Near-Earth Object Survey Act, should be archived in a publicly available database as soon as practicable after it is obtained. NASA should continue to support the utili zation of such data and provide resources to extract near Earth object detections from legacy databases and those archived in future surveys and their associated follow-up programs
