... The measured bolometric flux and corrected NPOI angular diameter yield an effective temperature of 8600+/-500 K. Least-squares comparisons of synthetic spectral energy distributions from 1220 Г: to 3.6 cm with the observations provide estimates for the effective temperature and the mass-loss rate of ~=8400+/-100 K and (8+/-3)Г-10-7 Msolar yr-1, respectively. ...

H I Self-Absorption (HISA) arises from cold H I gas in front of warmer H I emission at the same velocity. HISA is thus a unique probe of the velocity and temperature structure of the Galactic ISM, from sub-parsec scales within clouds up to multi-kiloparsec scales across the disk. ... To address this question, a series of simple H I radiative transfer models of the Galaxy will be presented. ...

The probability density function (PDF) is a simple analytical tool for determining the hierarchical spatial structure of molecular clouds. ... We have recently conducted a PDF analysis of the molecular gas in the G333 and Vela C giant molecular cloud complexes, using transitions of CO, HCN, HNC, HCO+ and N2H+. The results show that CO and its isotopologues trace mostly the log-normal part of the PDF, while HCN and HCO+ trace both a log-normal part and a power law part to the distribution. ...

... The distribution of galactic RCB stars is controversial. Several authors have argued that they belong to a thick galactic disk, and are thus old Population I stars. ... However, their distribution and space velocities suggest they may alternatively belong to the even older galactic bulge (Population II, [ Drilling 1986 ]). ... These are the only RCB stars for which a distance is known and hence for which an absolute magnitude can be deduced. ...

It is possible to incorporate in the SAS software packages that are not part of the official SAS distribution. These we call 'external packages'. All that is needed is to set the environment variable SAS_PATH to point to all directories that contain SAS components, in the form of a colon-separated list. ... He will have to set the SAS_DIR and SAS_PATH environment variable and call the sas-setup script (preferably in a login script), e.g. (csh): setenv SAS_DIR /usr/sas . ...
