SED of the East lobe of DA 240 calculated with a power-law spectrum recovering the low-ν radio data for p₁ = 1 and B_μ = 1.5 (red solid for the radio spectrum and red dotted for the high-ν spectrum) and p₁ = 10³B_μ = 0.87 (magenta dashed for the high-ν spectrum). The electron spectrum has a cutoff at p_cut = 5 × 10⁵ to produce an ICS-CMB gamma-ray emission below the Fermi-LAT 5-yr sensitivity limit that is exceeded for the case p₁ = 10³ with a power-law spectrum without high-ν cutoff. SSC SED model for the hot spot that fits the X-ray flux at 1 keV (open square point plus errorbars) with the synchrotron branch (cyan solid) or with the Compton branch (green dashed) is also shown for comparison. Various instrument sensitivities for point-like sources are shown for comparison. Instrument sensitivities are taken from the ASI-ASDC SED builder tool at http://tools.asdc.asi.it/.
