list. Ideally data mining tools need to point their users directly to the exact CCDs of such a mosaic camera possibly holding their fixed or mobile targets.\
In 2013 we provided [*Find CCD Subaru*]{}[^29] to search for known NEAs in the SuprimeCam archive [@Vaduvescu2017]. In 2016 we extended this work to other few cameras, namely VST-OmegaCam, INT-WFC, VISTA-VIRCAM, CFHT-MegaCam, Blanco-DECam and Subaru-HSC. This tool is named [*FindCCD*]{}[^30], being developed for NEA searches. It queries the SkyBoT server[^31] [@Berthier2006] to calculate positions of the known NEAs in the field and the NEODyS-2 server[^32] [@Chesley1999] to overlay the uncertainty ellipses for poorly observed NEAs. In Figure 6 we give an example of [*FindCCD*]{} plot for the very poorly observed NEA 2015 BS516 searched in a given Blanco-DECam image, where the uncertainty region (plotted in red) covers many CCDs.\
In March 2018 we released [*FindCCD for Double Stars*]{}[^33] to identify the particular CCD of few major mosaic cameras possible to hold known double stars from the Washington Star Catalog [@Curelaru2019].\
In June 2018 we deployed [*FindCCD for Fixed Objects*]{}[^34] to search for stars, galaxies or other fixed objects given as J2000 RA/DEC coordinates. Seven mosaic cameras are supported by March 2019, but we
