Query: Globular cluster abundances in the light of 3D hydrodynamical model
  atmospheres   The new generation of 3D hydrodynamical model atmospheres have been employed
to study the impact of a realistic treatment of stellar convection on element
abundance determinations of globular cluster stars for a range of atomic and
molecular lines. Due to the vastly different temperature structures in the
optically thin atmospheric layers in 3D metal-poor models compared with
corresponding hydrostatic 1D models, some species can be suspected to be
hampered by large systematic errors in existing analyses. In particular, 1D
analyses based on minority species and low excitation lines may overestimate
the abundances by >0.3 dex. Even more misleading may be the use of molecular
lines for metal-poor globular clusters. However, the prominent observed
abundance (anti-)correlations and cluster variations are largely immune to the
choice of model atmospheres.
