OSTAR2002 Grid: Spectral Energy Distributions

Spectral Energy Distributions (SEDs) cover a wavelength range, 4.5 nm to 300 microns, for the full set of frequency points used to calculate the model atmospheres (180 000 to 200 000 frequencies). The SEDS are sampled with an irregular frequency step, depending on the set of atomic transitions included in the model atmospheres. If required, users can readily resample the SEDs at selected resolutions with constant frequency steps.

The tar archive files contain 69 two-column ASCII files for each model atmosphere:

- Frequency [s-1]

- Eddington Flux Hn at the stellar surface [erg s-1 cm-2 Hz-1]

SEDs are available for 10 scaled-solar chemical compositions:
