Query: NLTE abundances of Mn in a sample of metal-poor stars   Following our solar work, we perform NLTE calculations of the Mn abundance
for fourteen stars with [Fe/H] from 0 to -2.5, mainly to show how NLTE affects
Mn abundances in cool stars of different metallicities.The spectrum synthesis
and Mn abundances are based on statistical equilibrium calculations using
various estimates for the influence of hydrogen collisions.The NLTE abundances
of Mn in all studied stars are systematically higher than the LTE abundances.
At low metallicities, the NLTE abundance corrections may run up to 0.5 - 0.7
dex. Instead of a strong depletion of Mn relative to Fe in metal-poor stars as
found by the other authors, we only find slightly subsolar values of [Mn/Fe]
throughout the range of metallicities analyzed here. The [Mn/Fe] trend in
metal-poor stars is inconsistent with the predictions of galactic chemical
evolution models, where Mn is less produced than Fe.
