vo@fai.kzccd-observationphotometryoptical-observation Reduced, astrometrically calibrated CCD images obtained with telescopes operated by the Fesenkov Astrophysical Institute. The initial release contains observations from the Zeiss-1000 East telescope at the Tian Shan Astronomical Observatory; further FAI telescopes will be added as their reduced data become available. Discovery metadata remain public during proprietary periods. Before the RELEASE date, downloads contain the original FITS headers but zero-valued data arrays; afterwards the original FITS product is delivered.https://dachs.fai.kz/ccd_observations/q/browse/infoArchiveResearchIsServedByFAI archives ObscoreTian Shan Astronomical ObservatoryFesenkov Astrophysical InstituteCCD camerasOpticalivoaDefinition and support code for the ObsCore data model and table.ivoa.obscoreThis data collection is queryable in FAI archives's obscore table.ccd_observations Reduced, astrometrically calibrated CCD images obtained with telescopes operated by the Fesenkov Astrophysical Institute.
