Grid of radiative (DA) LTE spectra (convection inhibited by magnetic fields) Separate files for log (g) = 7.0, 7.5, 8.0, 8.5 and 9.0 Each file includes temperatures from 6000 K to 15,000 K. File format: 1) Grid of 1787 wavelength points in Angstrom 2) For each model at fixed gravity Header "Effective temperature = [value] gravity = [value] y = 0.000E+00" Grid of 1787 Fnu Eddington fluxes in air wavelength (units of erg cm^-2 s^-1 Hz^-1) Main references Gentile Fusillo N.

(2009) ApJ, 696, 1755. 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.
