Spectral energy distribution (SED) of the γ-ray emission originating from the direction of UKS 1, as observed by Fermi-LAT (black data points). The blue dashed-line is the best-fit PL model. The shaded region illustrates the uncertainty of this model. The PLEC fit is also plotted for comparison. Both models and LAT data in this plot are the results with the surrounding excess sources removed. The estimated energy flux derived from the differential flux given by the 3HWC data at 7 TeV is shown in red.
