The best task to correct the flux scale of an observation is mfboot - mfboot performs an analagous function to gpboot . ... It works by scaling the antenna gain table so that the flux density scale of the observed data agrees with some model. ... Task mfboot can also be used when bootstrapping from a point source. ...

... We have used a coupled dynamical and chemical model to examine the chemical changes caused by the passage of a density wave propagating into the protostellar cloud. ... The chemical coupling between gas and dust causes locally increased number densities of active ra dicals, such as C, N, O, NH, and OH, and hydrogen saturated molecules CH 4 , NH 3 and H 2 O. We show that chemical evolution in the post-wave gas can account for the observed abundance of water and NH 3 observed in interstellar clouds. ...

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. ...

... Because of the Sun 's UV radiation, Earth 's upper atmosphere is partly (0.1% or less) ionized plasma at altitudes of 70-1500 km. ... Around the plasma density maximum (F-layer, see below) a so-called ionospheric waveguide is formed for magnetosonic waves . ... It is interesting to note that this works also the other way round and, for example, the auroral kilometric radiation created by the precipitating particles high above the ionosphere does not reach the ground because of the ionospheric E...

We report the density structure of the ultracompact HII regions G35.20-1.74, G9.62+0.19-E, and G75.78+0.34-H2O. The density profiles are derived from radio continuum emission at wavelengths from 6 to 0.3cm. In the case of G35.20-1.74, a cometary UC HII region with a core and a tail, the spectrum of the core varies as Snu~nu^(0.6), implying that the density structure is ne~r^(-2). ...
