The NAROO digitization center

The New Astrometric Reduction of Old Observations (NAROO) center can be found at the Paris Observatory in Meudon, and it is dedicated to measurement astrophotographic plates analysis old observations. NAROO digitizer consists a granite-based Newport-Microcontrol open-frame air-bearing XY positioning table, scientific sCMOS camera, telecentric optical system. plate holder assembly suited for mounting glass up 350 mm squared. machine stability better than 15 nm, its repeatability 40 nm. With real photographic data, we were able produce measurements with an accuracy 65 renewed interest about concerns expansion database transient objects evolving time, since digitization now makes possible measure images high level identify all available objects. information extracted from such materials astrometric, photometric, spectroscopic nature, when not purely imaging, consequences planetology, near-Earth asteroid risk assessment, astrophysical phenomena, general relativity, mention but few. Through our program Gaia era, detail examples current upcoming uses community. We invite researchers use facilities digitize their collection by answering call proposals.
