He+C+N+O NLTE Models

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.

These fluxes are calculated from models with "typical" PG 1159 star abundance ratios: He:C:N:O=33:50:2:15 by mass.

Note: The following tables are not suitable for precise spectral analyses because only approximate formulae were used in order to account for Stark line broadening and multiplet splitting is not considered.

NLTE model atmosphere fluxes (5 - 2000Å)
calculated for the use with the photoionization codes CLOUDY and MOCASSIN.
The flux is binned to 0.1Å intervals.
In all files the effective temperature calculated from the integrated flux is given. The flux may be normalized to the correct effective temperature.
