Grid of 1D pure-hydrogen NLTE synthetic spectra

Separate files for log (g) = 6.5, 7.0, 7.5, 8.0, 8.5, 9,0 and 9.5.
Each file includes 60 temperatures from 1500 to 140,000 K.

Convection model is 1D ML2/alpha = 0.8.

NLTE is switched off below 40,000 K as it is negligible at low and medium spectroscopic resolution.
NLTE corrections for line cores <20,000 K at high spectroscopic resolution are available upon 
request to the authors.

File format:

 2) For each model at fixed gravity

Conversion:

The flux at Earth is f = 4*pi*R^2/D^2 * Eddington flux

where R is the white dwarf radius, D the distance and the Eddington flux 
the quantity in the files. The radius can be found from Evolutionary Sequences.

For spectroscopic fitting 3D corrections should be added for accurate atmospheric parameters. For photometric fitting 1D models are sufficient but please check the 3D grid and reference below for UV photometry.
