Title: Identifying New γ-Ray Sources in All-Sky Surveys Based on Fermipy’s Advanced Algorithm
Authors: Yunchuan Xiang, Peng Feng, and Xiaofei Lan
================================================================================
Description of contents:  

4FGL-Xiang.fits: This file contains two sub-tables: one listing the new GeV sources and the other listing the new GeV extended sources.
4FGL-Xiang_Region_File.reg: This region file includes all gamma-ray sources across the sky, encompassing our newly discovered GeV sources as well as all sources from 4FGL-DR4.
4FGL-Xiang_Region_File_No_Name.reg: This file contains the same information as 4FGL-Xiang_Region_File.reg but excludes the names of the sources from 4FGL-DR4.
500MeV_TSmap_fits.rar: This archive contains the TS maps of 72 ROIs in FITS format, for energies above 500 MeV.
500MeV_TSmap_eps.rar: This archive contains the TS maps of 72 ROIs in EPS format, for energies above 500 MeV.
Table4.xlsx: This file contains the analysis results of the robustness verification.


Given that some regions have a high density of sources, we strongly advise readers to use the following command (1) to 
obtain detailed information about the spatial distribution of each new source:

ds9 run_500MeV_tsmap_R*.fits -cmap b -region 4FGL-Xiang_Region_File.reg   (1)

where * denotes the ROI number.
