Observational hints of a real age spread in the young LMC star cluster
  NGC 1971
  We report the serendipitous young Large Magellanic Cloud cluster, NGC 1971,
exhibits an extended main-sequence turnoff (eMSTO) possibly originated by
mostly a real age spread. We used CT1 Washington photometry to produce a
colour-magnitude diagram (CMD) with the fiducial cluster features. From its
eMSTO, we estimated an age spread of ~ 170 Myr (observed age range 100-280
Myr), once observational errors, stellar binarity, overall metalicity
variations and stellar rotation effects were subtracted in quadrature from the
observed age width.
