Steady-state SSC model computed using ATHEvA and LeHaMoC codes. We show a comparison of (from top to bottom): the steady-state electron spectra, photon spectra, and production rate of pairs due to γγ absorption. The bottom panel of each plot shows the ratio χ of the spectra computed with ATHEvA and LeHaMoC. All displayed spectra are measured in the comoving frame of the blob. The parameters used for this test can be found in Table 2 under the column Test 1.
