Sterne 2.3 + Spectrum : high-resolution spectra

Spectra calculated using the QUB LTE code Spectrum containing the principal diagnostic lines of H, HeI, HeII, C, N, O and Si used in studies of early-type stars.

Line 1

LABEL
provides information on the effective temperature, surface gravity, composition and microturbulent velociity of model. Compare with line 1 of the model structure.

Line 2

NW
The number of wavelength points in the spectrum

Line 3

SYNTHETIC SPECTRUM : F_NU
States that the fluxes are given in frequency units

Line 4

blank

Line 5

Column headers

Line 6 onwards

Wavelength (Angstrom), Normalized flux, Total flux, Continuum Flux, Reference depth (tau_ref) where optical depth tau = 1. Flux units are in erg/cm^2/s/Hz.
