The modelling of the RGB J0710+591 spectral emission. The upper panel shows the first approach where we considered the Swift and Fermi observations only. In the lower panel, we demonstrate an alternative approach that can explain the origin of the TeV emission observed by VERITAS. Note that the Fermi and the VERITAS observations were not simultaneous. To obtain the observed IC spectra, we used the EBL lower-limit model proposed by Kneiske & Dole (2010), where the dashed lines show the intrinsic unabsorbed emission.
