Left panel: J-band, integrated spectra of the six LMC globular clusters. The shaded areas indicate the regions with contamination by strong OH and O₂ sky line residuals. Right panel: H-band, integrated spectra of four of the LMC clusters. Due to unstable atmospheric conditions, the H-band spectra of NGC 1754 and NGC 2005 are heavily contaminated by sky line residuals and thus exibit a very low S/N and are not shown. Each spectrum is normalised to its median value. Line identifications are based on the stellar spectral atlases by Lançon & Rocca-Volmerange (1992), Wallace et al. (2000) and Rayner et al. (2009).
