Description:
SP_ACE computes stellar parameters (gravity, temperature) and element abundances from optical stellar spectra (`sample spectrum`_). It employs 1D stellar atmosphere models in Local Thermodynamic Equilibrium (LTE). The present service does not offer all the options available for SP_Ace as documented in `the tutorial`_. All options are available if running SP_Ace locally (cf. `download page`_). This service exposes an updated version containing some bug fixes with respect to the one described in the paper. .. _the tutorial: http://dc.g-vo.org/sp_ace/q/dist/static/tutorial.pdf .. _download page: http://dc.g-vo.org/sp_ace/q/dist/static .. _sample spectrum: http://dc.g-vo.org/sp_ace/q/c/static/fast_spectrum.txt

Description:
The Tübingen NLTE Model-Atmosphere Package (`TMAP <http://astro.uni-tuebingen.de/%7ETMAP/TMAP.html>`_) 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.
