Description

the attached pdf shows the incident wmbasic SED, and the predicted total emission, for a hot wind around a star. The input script is also attached. This was run with r4683 gcc/mac.

a few curiosities in this plot;

the wmbasic incident SED stops at 1e-5 eV. This is not the plasma frequency (that is near 1e-6 eV). Why don't we extrapolate the stellar SED to the low-energy end of the continuum using a Rayleigh-Jeans slope?

There is a discontinuous derivative in the stellar SED at about 1e-2 eV.

The feature that really grabs the eye, and must be bogus, is the large "absorption line" in the total emission at about 1e-6 eV. This is near the plasma frequency and may be some sort of off by one error.

The radio / FIR is optically thick to brems, which may account for the changes in slope between 1e-6 and ~1e-4 eV.
