Table 1: Overview of the observed LMC targets. The targets Sk -67 5 and Sk -70 120 are comparison stars used for telluric correction and stellar line identification. Adopted \ensuremath {E_{B-V}} values are corrected for Galactic foreground extinction (see Table 3). The final magnitudes and colour indices are on the photometric system defined by Landolt (1992). The ${\it UBV}$ optical photometry for the remainder of the LMC stars was taken from Misselt et al. (1999) and Gordon et al. (2003).
