In the framework of the Virtual Observatory, the GAVO project provides theoretical spectral energy distributions (SEDs) of TMAP NLTE model atmospheres within the GAVO TheoSSA service. All SEDs from this model-atmosphere grid are available in a VO-compliant form within TheoSSA.
The model-atmosphere grids are calculated for effective temperatures Teff = 450 000 - 1 050 000 K, in 10 000 K steps. The surface gravity is log g = 9. These fluxes are calculated from models with different abundance ratios. [X] denotes log (stellar mass fraction/ solar mass fraction) of species X. IG is a generic model atom including Ca - Ni.
The picture shows the abundances in the model series.
[X] denotes log (abundances / solar abundance)

The FITS files are to be used as atable within XSPEC.
The flux is binned to 0.002Å and 0.5Å intervals within 10 - 60Å and 10 - 8000Å, respectively.
The FITS files contain tables with the same surface gravity (log g = 9).
