Description Benchmark based on GalaxyZoo
A small sample of the GZ-DECaLS dataset to cheaply test the ability of vision-language models to describe galaxy images.
Data source
The underlying catalog data are derived from the Galaxy Zoo DECaLS: Detailed Visual Morphology Measurements from Volunteers and Deep Learning for 314,000 Galaxies and remain subject to their original data-use policy and required acknowledgements.
