Stellar SEDs for α Cen A (blue) and B (orange) binned to 1 Å. The SED of the Sun, scaled to a distance of 1.33 pc, from T. N. Woods et al. (2009) is shown in gray for comparison. Colored background regions show the various regions described in Section 5.2. The regions containing the reconstructed Lyα (1214–1217 Å, Section 5.2.4) and SISTINE detector gap (1270–1300 Å, Section 5.2.3) are not colored for clarity. The PHOENIX model extends to 10⁷ Å but we have restricted the y-axis to 10⁻¹⁷ erg s⁻¹ cm⁻² Å⁻¹, again to aid visual clarity of features within the main spectra.
