... 1Wills Accurate measurements of relative flux density have been made between frequencies of 468 and 5009 MHz for 300 radio sources selected from Parkes catalogue. ... Excluding the incertainties in scaling these flux densities to an absolute system, rms errors vary from 0.24 Jy and 2.4 % at 635 MHz to 1.8 % at 2700 MHz; uncertainties in "absolute" scaling are thought to be about 45 %. ... Some sources whose spectra may be useful for flux density calibration are noted. ...

We have studied scaling relations (virial mass versus CO luminosity, luminosity versus size, linewidth versus size) for molecular clouds in the 30 Dor and N 159 regions in the Large Magellanic Cloud. ... The study of molecular clouds in the Galaxy has resulted in a number of scaling relations between global cloud properties such as mass, density, luminosity, size and velocity dispersion (e.g. Larson (1981) , Scoville & Sanders (1987) , Solomon et al. ...

... Our main goal was to study the large-scale distribution of the molecular gas in the Serpens region and to understand its relation with the denser gas in the cloud cores, previously studied at high angular resolution. ... The 13CO and C18O(1--0) maps of the centroid velocity show an increasing, smooth gradient in velocity from East to West, which we think may be caused by a global rotation of the Serpens molecular cloud whose rotation axis is roughly aligned in the SN direction. ...

... Impedance . Electrical impedance, or simply impedance, describes a measure of opposition to a sinusoidal alternating current (AC). Electrical impedance extends the concept of resistance to AC circuits, describing not only the relative amplitudes of the voltage and current, but also the relative phases. ... Resistance is the real part of impedance; a device with a purely resistive impedance exhibits no phase shift between the voltage and current. ...

... Early on, our interest in chirping analysis functions was motivated by a different kind of chirping phenomenon: chirping due to perspective. ... Our interest in radar, however, drew us toward processes that are more accurately analyzed by linear-FM chirplets. ... We have also constructed other chirplet transforms, such as a three-parameter Doppler chirplet representation that models a source producing a sinusoidal wave, while moving along a straight line (e.g. a train whistle). ...

... The optical spectrum of the early B hydrogen-deficient star LSIV+6 deg2 has been analysed. With T_eff=31000K, logg=4.05, n_H~10^-4 and n_c~0.1 (relative abundances by number), it is the hottest high-gravity extreme helium star (EHe) yet studied. ... LSIV+6 deg2 is a comparatively metal-rich EHe star; abundances of C, N, O, Ne, Mg, Al and P are typical of other EHes, whilst Si and S are somewhat deficient. ...
