AutoSourceID-Light: Optical Telescope Images with Gaia Source Catalogs

Three optical fields from the MeerLICHT telescope, including Omega Centauri and Fornax galaxy cluster images, are paired with catalogs of Gaia EDR3 sources. This dataset supports the AutoSourceID-Light framework for rapid source localization in astronomical images. The data was created by Fiorenzo Stoppa of Radboud University Nijmegen and is associated with a published paper and code repository.

Use Cases

• Training computer vision models for astronomical source detection based on optical telescope imagery.
• Benchmarking source localization algorithms against known Gaia EDR3 source catalogs.
• Developing multimodal AI systems that fuse optical image data with tabular catalog data.

Strengths

• Data is associated with a published research paper and a publicly available code repository.
• Includes data from three distinct astronomical fields, including a galaxy cluster and an 'empty' control field.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
