title: Toward a Unified Scheme of Blazar Evolution

description: # Fermi Blazar Classification Catalogue


This catalogue contains the results of our study on the characterization of the Fermi blazar population, as described in:


Oukacha, E. and Becherini, Y. (https://arxiv.org/abs/2507.03088)


The dataset includes the following columns:


- Name: Source name as listed in the 4LAC catalog

- embeddings_0: First dimension of the reduced latent space learned by TabPFN

- embeddings_1: Second dimension of the reduced latent space

- Proba_BLL: Classification probability that the source is a BL Lac, as predicted by TabPFN


This dataset is provided to support reproducibility, enable further validation of our results, and facilitate future studies involving the blazar population observed by Fermi-LAT.
