Instrument Summary -- Why Use the GHRS? Here we provide a brief overview of the basic properties of the GHRS. ... The GHRS can obtain spectra from about 1150 to 3200 . ... The repeatability of fluxes is even better, being better than 1%; i.e., it is possible to compare measures of the same wavelength in the same star at different times to within 1% for observations with the LSA. ... The source to be observed may be placed in a Large Science Aperture (LSA) or a Small Science Aperture (SSA). ...

... 7.1 Introduction to media types . ... 7.3 Recognized media types . 7.3.1 Media groups One of the most important features of style sheets is that they specify how a document is to be presented on different media: on the screen, on paper, with a speech synthesizer, with a braille device, etc. Certain CSS properties are only designed for certain media (e.g., the 'cue-before' property for aural user agents). ... For example, the 'font-size' property is useful both for screen and print media. ...

... Physical Properties of Crystals . ... The course is an introduction into crystal physics and consists of two introductory parts devoted to the basics of crystallography and tensor analysis and six main chapters in which the physical phenomena in anisotropic medium are described by the example of the elastic, electrical and magnetic crystal properties. The effect of symmetry is also discussed. ... Effect of symmetry on crystal properties. ... Effect of symmetry on crystal optical properties. ...

... A cyclic convolution of an input image weighted by gives output according to the following prescription: . ... The Fast Fourier Transform (FFT) algorithm used by the task works most efficiently if each dimension of the image is a multiple of 2, 3, 5 or 7. ... If the image is large and the number of convolvers small, this will generally be the FFT method; however direct convolution becomes more efficient if the image is divided into many small patches of different convolution. ...

Next: Survey Methods Up: THE DEEP X-RAY RADIO Previous: THE DEEP X-RAY RADIO . Blazars are the most extreme variety of AGN known. ... The beaming hypothesis has been successful in reproducing the luminosity function of samples of blazars (e.g., Padovani & Urry 1990, 1991, 1992; Urry, Padovani & Stickel 1991), allowing the derivation of class properties such as the range of Lorentz factors and opening angles in the radio band (and also in other bands for BL Lacs). ...

... The sky distribution of the BCGs from the HSS sample is shown in Fig. 6 together with BCGs from the SBS and Case surveys (Izotov et al. [ 1993b ]; Pustilnik et al. ... First, we compare the apparent magnitude distributions of the three samples. ... The similar behaviour of the faint end of the apparent magnitude distributions infers that the Northern BCG sample may have a similar completeness down to this limiting magnitude. ...
