Theoretical Priors and Processed Band Data for Automated ARPES Reconstruction of RbTi3Bi5 and Au111

This dataset contains the theoretical results and pre-processed band structures for the kagome-lattice compound RbTi3Bi5, supporting the automated band reconstruction framework described in our study. The repository is organized into two primary components: Theoretical Priors: Raw eigenvalues and band structures obtained via first-principles Density Functional Theory (DFT) calculations. These results characterize the intrinsic electronic structure of RbTi3Bi5 and serve as the physical ground truth for experimental alignment. Processed Datasets: Theoretically derived bands that have undergone coordinate transformation and momentum scaling. These datasets are specifically formatted for direct integration into the Band Structure Fidelity Index (BSFI) and the Markov Random Field (MRF) optimization model. Usage Note: These data allow researchers to reproduce the energy-momentum alignment and the subsequent band extraction process for \ce{RbTi3Bi5} ARPES spectra. Users can leverage these priors to test different reconstruction hyperparameters or apply similar physics-informed algorithms to related kagome systems.
