Significance maps of the Fermi-LAT data around the position of 4FGL J1813-1737e in the energy range from 1 GeV to 1 TeV, with a correlation radius of 0.1°. Left: the position of the Galactic plane is indicated by the dashed line, the pulsar position is indicated in blue, and 3σ and 5σ contours are depicted. Right: significance map of the region after subtracting the emission using an elongated Gaussian model and a symmetric Gaussian model. The 1σ Gaussian extent of the models is depicted by the black dashed lines.
