The NextGen Model Atmosphere Grid for 3000 \le Teff \le 10,000 K Hauschildt, PH, Allard, F and Baron, E., 1999, Astrophysical Journal, 512, 377 (LTE), 3000 - 10,000 K, steps of 200K, log g 3.5 to 5.5 in steps of 0.5, and metallicity of 10**-4 of solar to solar. Name of Code is PHOENIX. URL is http://dilbert.physast.uga.edu/~yeti. They are working on an extension towards lower Teff for very low mass stars and brown dwarfs. This requires improved molecular opacities and better atomic data for molecules.
(from the README file for the visatl atlas) An Atlas of the Spectrum of the Solar Photosphere from 13,500 to 28,000 cm-1 (3570 to 7405A)
L. Wallace, K. Hinkle, and W. Livingston, National Optical Astronomy Observatories.
The files collected here were made in conjunction with, and are intended to be used with, the hard copy of this atlas. The files with the prefixes "sp" contain the spectral data from which the plots were made. Each of these contains a 50 cm-1 region with a 3 cm-1 overlap on each end. Following the prefix "sp" is the lead frequency of the segment, e. g., "14150". For the region 13,500 to 20,000 cm-1, the four columns of each file contain, first the frequency, second the deduced telluric spectrum, third the observed photospheric spectrum before correction for telluric absorption, and fourth the photospheric spectrum corrected for telluric absorption. The region 20,000 to 28,000 cm-1 contains no sensible narrow-line telluric absorbers and consequently the files contain only the frequencies and the observed spectrum. The required multiplicative factors to correct the observed frequencies to the laboratory scale are 1.0000013 for 13,500 to 16,000 cm-1, 0.9999981 for 16,000 to 20,000 cm-1, and 1.0000018 for 20,000 to 28,000 cm-1.
The remaining files are encapsulated post-script files, one per atlas page. The prefix "ph" indicates the corrected photospheric spectra in Section II of the atlas. The "tr" files are the Section III pages giving atmospheric transmission and the observed photospheric spectra. Finally, "cph" and "ctr" are the compressed photospheric and transmission plots of Section I.
