No evidence for younger stellar generations within the intermediate age
  massive clusters NGC 1783, NGC 1696 and NGC 411
  Recently, Li et al. (2016) claimed to have found evidence for multiple
generations of stars in the intermediate age clusters NGC 1783, NGC 1696 and
NGC 411 in the Large and Small Magellanic Clouds (LMC/SMC). Here we show that
these young stellar populations are present in the field regions around these
clusters and are not likely associated with the clusters themselves. Using the
same datasets, we find that the background subtraction method adopted by the
authors does not adequately remove contaminating stars in the small number
Poisson limit. Hence, we conclude that their results do not provide evidence of
young generations of stars within these clusters.
