Data Overview
AstroVision uses a single image survey — Galaxy10 DECaLS — and enriches it with a photometric cross-match and two morphometry tables. All sizes below are read from the documentation data pack.

Coverage differs by modality
Only a fraction of galaxies carry each auxiliary modality: morphometry exists for 5,000 of 17,736 images and absolute magnitudes for 5,651. The fusion model masks missing values rather than dropping galaxies.
