Determination of reddening and age for ten Large Magellanic Cloud star
  clusters from integrated spectroscopy
  We present flux-calibrated integrated spectra in the optical range (3700-6800
\AA) obtained at Complejo Astron\'omico El Leoncito (CASLEO, Argentina) for a
sample of 10 concentrated star clusters belonging to the Large Magellanic Cloud
(LMC). No previous data exist for two of these objects (SL 142 and SL 624),
while most of the remaining clusters have been only poorly studied. We derive
simultaneously foreground $E(B-V)$ reddening values and ages for the cluster
sample by comparing their integrated spectra with template LMC cluster spectra
and with two different sets of simple stellar population models. Cluster
reddening values and ages are also derived from both available interstellar
extinction maps and by using diagnostic diagrams involving the sum of
equivalent widths of some selected spectral features and their calibrations
with age, respectively. For the studied sample, we derive ages between 1 Myr
and 240 Myr. In an effort to create a spectral library at the LMC metallicity
level with several clusters per age range, the cluster sample here presented
stands out as a useful complement to previous ones.
