Continuum-normalized FIES spectrum of CoRoT 102899501 obtained on 2010 October 1 in the lithium line region. The template spectrum of a lithium-poor reference star broadened at the v sin i of CoRoT 102899501 and Doppler-shifted according to the RV difference is shown in dotted line. The lithium absorption is cross-hatched in the difference spectrum whose continuum has been set arbitrarily at a 0.5 level.
