A curated, band-organised launchpad to the survey and mission catalogues that working astronomers actually reach for. Each card gives you depth, sky-coverage, angular resolution, key data products, primary references, and a one-click jump to the canonical VizieR table family — plus the native archive when that's where the science-grade data really lives. Ground & space, radio through gamma-ray, 212 entries spanning the last fifty years of multiwavelength astronomy. Compiled for quick mental triangulation across the spectrum, not as a complete index of VizieR's ~25,000 tables — that's what VizieR's own search is for.
