It is passed to Apache through the ZINET XPARM field since ZINET is the only way to start the server on TPF. A third group of options apply to both the informational displays (ZFILE) and running the server (ZINET XPARM): -d, -D and -f. The rest of Apache's options are either not applicable or are not supported on TPF. ...

Abstract -- The strengths of magnetic fields in interstellar gas clouds are obtained through observations of the circular polarization of spectral line radiation. ... To infer information about these irregularities from the observational data, we develop statistical relationships between the rms values of the irregular component of the magnetic field and spatial variations in the circular polarization of the spectral line radiation. ...
