Co-added AAOmega spectra (panels a) and b)) and CCFs (panels c) and d)) of four BEER candidates with different effective temperatures. For clarity, successive spectra were shifted upward by 1 and successive CCFs were shifted upward by 0.55. CoRoT IDs and estimated temperatures of the four candidates are indicated in panel c). Blue-arm spectra and their CCFs are shown on the left (panels a) and c)), while red-arm spectra and their CCFs are shown on the right (panels b) and d)). Wavelengths of Ca II and hydrogen lines are taken from Kramida et al. (2013).
