Left-hand panel: SED of V8: black filled circles correspond to the observed photometry at m_F435W, m_F606W, m_F814W (from the HST) J, H, K_s (from 2MASS), N_8.6   μm (from VISIR), plus 9 and 18   μm from AKARI. The dotted dashed black line is the best-fitting black-body with a temperature of of 2900   K. The VISIR N_8.6   μm filter transmission curve is shown in red, while that of AKARI 9   μm is shown in shaded blue. The middle panel displays a comparison of the VISIR (solid black line) and IRS (dashed blue line) spectra. The shaded areas highlight the flux calibration uncertainties estimated for the two spectra. The right-hand panel shows the MIR excess for V8 (continuum subtracted spectrum) where the features at 9.7 and 11.5   μm are highlighted with vertical dotted lines.
