The Tübingen NLTE Model-Atmosphere Package (TMAP
_) is a tool to calculate
stellar atmospheres in spherical or plane-parallel geometry in hydrostatic
and radiative equilibrium allowing departures from local thermodynamic
equilibrium (LTE) for the population of atomic levels./TMAP/ is based on
the so-called Accelerated Lambda Iteration (ALI) method and is able to
account for line blanketing by metals. All elements from hydrogen to nickel
may be included in the calculation with model atoms which are tailored for
the aims of the user.
