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.

TheoSSA provides spectral energy distributions based on model
atmosphere calculations. Currently, we serve results obtained using
the Tübingen NLTE Model Atmosphere Package (TMAP) for hot compact
stars.
