Appendix A: Figures A.1 and A.2 and Table A.1

thumbnail Fig. A.1

Velocity-corrected spectra of Tc 1 (in black) and HR 6334 (in red) around 3760 Å (left panel) and 4000 Å (right panel) where the atomic line identifications are indicated (in green). The expected positions (and FWHMs) of the C60 features are marked on top of the spectra. There is no evidence (additional absorption) in Tc 1 for the neutral C60 features at 3760, 3980, and 4024 Å. The residual spectrum (in cyan) obtained by subtracting the oxygen lines around 3760 Å is also shown.
