These machine-readable tables include the data presented in Section 8 and the Appendix C of the paper "Exploring the nature of Galactic unassociated sources detected by the Fermi-LAT". The GU_table.mrt aggregates the information of the three tables 5, 6, and 7, and the Appendix C. The file4FGL-DR4_prior_shift_prob_cat.csvcontains the probabilistic classification of sources in the prior shift model including an additional Guassian component (Section 3).The corresponding summary file that contains definitions of the groups is4FGL-DR4_prior_shift_summary.csv The file4FGL-DR4_cov_shift_prob_cat.csvcontains the probabilistic classification of sources in the covariate shift model presented in Appendix A.The corresponding summary file that contains definitions of the groups is4FGL-DR4_cov_shift_summary.csv The file4FGL-DR4_cov_shift_vs_prior_shift_prediction.csvcontains a comparison of predictions for the prior and covariate shift models.The column RF_prob contains the largest probability for a class in covariate shift model, while the column RF_class contains the corresponding class in the covariate shift model (determined with the random forest method).The columns PDF_prob and PDF_class contain correspondingly the highest probability and the corresponding class in theprior shift model (determined with the PDF method).The column Gauss_PDF contains separately the Gaussian component probability in the prior shift model.
