... December 21, 1997 . ... Advantages are briefly discussed of gaining in spectral resolution, which is accompanied by losses in signal level, as compared with the attempts to improve the accuracy of measurement of line parameters by means of rising the S/N ratio alone with increasing the exposure time. To partially solve the problem of observations of faint objects at the BTA a new design echelle spectrometer is proposed. high resolution spectroscopy . ...

Fair" UV Coverage for a Multi-resolution John Bunton, CSIRO Telecommunications and Industrial Physics, Australia Introduction If we wish to have a multi-resolution telescope with equal point source sensitivity at all resolutions then we must accept that the baseline distribution of the correlations is predetermined. ... This occurs for each added step in resolution. ... It is seen that for the combined telescope the total number of correlations is 5.17 times the number needed for a single resolution. ...

Figure 2 Microcalorimeter resolution example. The two pannels in the plot show histograms of the filtered pulse heights that result from left: random samples of the microcalorimeter voltage (a measure of the intrinsic detector resolution) and right: pulses from the absorption of Mn K-alpha x-rays. The smooth curves are gaussian profiles with the FWHM as labeled; in the right pannel the gaussian profile has been convolved with the shape of the Mn K-alpha x-ray line doublet. ... 617) 495-7062 . ...

... After hearing and discussing Rocket-Space Corporation Energy General Designer U.P.Semevov's report on the fulfilling the flight program of the orbital complex Mir and proposals on its further exploitation, the Council draws attention to: . ... According to the Russian Government Resolution No. 76 of January 21, 1999 a large amount of work to find and attract Russian and foreign investments to provide the further exploitation of the orbital station Mir was carried out. ...

... In order to overcome undersampling, two or more frames of the same field may be obtained which are shifted with respect to each other by fractions of a pixel. ... Obviously science programs such as photometry of dense star fields and the morphological classification of distant galaxies would benefit from a method allowing a proper combination of two or more ``dithered'' WFPC-2 frames, i.e., frames that are shifted with respect to each other by fractions of a pixel. ...

Static Fourier spectrometers are often used for spectral measurements of the ionosphere emissions. There are two main advantages of Fourier spectrometers (FS) - large geometric factor and high spectral resolution; these parameters are two orders better than for grating spectral instruments. ... In scanning Fourier spectrometer optical and electric modulation of signal is used to avoid this problem, for static Fourier spectrometer there are no such ways. ...

Astrophotography Forum Message . ... The resolution of a CCD camera does not depend on the number of pixels in the camera, rather it depends on the size of the pixels making up the chip and the focal length of the lens forming the image. ... A larger chip made from the same substrate will have identical pixel sizes, just more of them. ... With a fixed focal length telescope we don't have that luxury, in which case smaller pixel size rather than larger chip size is the only way to increase resolution. ...

Solar High Resolution Studies . Back to . Solar Group . ... The study of photospheric "quiet" structures can have deep implications for a large variety of astrophysical topics, ranging from energy transport in astrophysical plasmas, to MHD problems in fluids with elevated Reynolds number. The wealth of structures and scales visible in the quiet solar photosphere is well exemplified in this white light movie, obtained at the Dunn Solar Telescope at the NSO/Sacramento Peak on Oct. ...

... An Annular Solar Eclipse at High Resolution . ... The event was not a total eclipse of the Sun for any Earth-bound sky enthusiast but rather, at best, an annular eclipse , where the Moon blocked most of the Sun. ... Those who witnessed the solar eclipse from a narrow path through Spain and Africa , however, were lucky enough to see the coveted Ring of Fire , a dark Moon completely surrounded by the brilliant light of the distant Sun. ...
