and Subaru-HSC), also plotting the uncertainty ellipse for poorly observed NEAs. In 2017 we improved [*Mega-Precovery*]{}, which offers now two options for calculus of the ephemerides and three options for the input (objects defined by designation, orbit or observations). Additionally, we developed [*Mega-Archive for Fixed Objects*]{} (MASFO) and [*Mega-Archive Search for Double Stars*]{} (MASDS). We believe that the huge potential of science imaging archives is still insufficiently exploited. In this sense, defining and making available a standard format for indexing meta-data needed to access the image archives could strongly enhance their use. We recommend to IAU to define such a standard and ask the astronomical observatories to adopt it for indexing their image archives in a homogeneous manner, and make these indexes available up to date, free of any proprietorship period.'
