... The J, H and K bands are characterized by a bright background, such a background is mainly due to the emission of atmospheric lines and of thermal radiation. ... If the source cover a large fraction of the slit, spectra off-source must be observed to adequately sample the sky background. ... The on chip integration time (time spent in each position of the slit) must not exceed 40 seconds in J and H bands and 60 seconds in K band. ... We suggest a sequence of 10 for each elementary integration time. ...

The close position of main satellite and subsatellite (distance between them about 1000 km) and using the similar sets of Faraday cups (VDP and VDP-S) with high resolution measurements (up to 16 Hz for the main satellite and up to 10 Hz for the subsatellite) allow us to determine the small-scale variations of the magnetopause shape and position and to estimate the velocity of the magnetopause motion. ... Two point observation of the magnetopause motion: the INTERBALL project. ...

Column 4 gives the eye-estimated apparent blue magnitudes according to the same sources. ... Other names of a galaxy we give in column 7. ... In column 3 we cite the original emission-line code of the galaxy for the strength of [O III ] doublet according to the Case catalog (s - strong, m - medium, w - weak). ...

... Binary orbits in the acceleration/period plane . Circular Orbits . ... We first present the equations for the period and acceleration of a pulsar in an eccentric binary system as a function of its position in the orbit. ... In Freire, Kramer & Lyne (2001) (from where most of this text and following equations are taken), we describe in more detail how circular binary orbits can be determined from the observed periods and accelerations of the pulsar. ... where is the orbital period of the binary. ...

Aristarch is Copernic of Classic World. ... First Aristarch determined the fact for how many times the Sun was father then the Moon and then he compared the Sun and the Moon with the Earth. ... Only the Moon rotates around the Earth. ... Gipparch suggested that the Sun turned around the Earth steady and in circumference but the Earth is displaced according its centre. ... The orbit point in which the Sun is nearer to the Earth Gipparch called perigee and the most remote one he called apogee . ...

... This class is designed to be an up to date summary of the last 10-20 years of observations relevant to Cosmology. ... Theory today is bombarded by a vast array of observational data but there remains no clear and preferred model for the origin and evolution of structure in the Universe. ... The inflationary paradigm and the nature of the Dark Matter - Inflation solves a lot of problems that are inherent in the standard Big Bang Model. ...

Next: SAS processing Up: Maintenance procedures Previous: Maintenance procedures Contents . Suitable observations should be longer than about 20 ksec, cover all the considered time period, and have different background levels, in particular the highest ones, so the sample should include observations taken at the beginning and end of the science window. It is helpful to consider objects for which no RGS spectrum is expected or to look at the RGS monitor pages. ... Michael Smith 2011-09-20 ...

... According to the most popular cosmological paradigm, the greater part of the galaxy mass is accumulated in the dark matter halo. ... The polar ring galaxies (PRGs) reveal external rings or disks of gas, dust and stars rotating in a plane roughly perpendicular to the disk of the central galaxy. ... The shape of the dark halo in the model was chosen so as to achieve the best fit to the observed rotation of both galaxies themselves and their polar rings. ... The SPRC-7 galaxy. ...

... Follow these steps to get the package and install it. ... Specify this as an environmental variable drsRoot: mkdir /cool2/jaffe/ews setenv drsRoot /cool/jaffe/ews (csh) export drsRoot=/cool/jaffe/ews (sh) This assignment must be made whenever you want to use EWS, so it is most convenient to put it in a .login, .profile,.alias.... type file. ... After fixing cfitsio/Makefile, return to $drsRoot and type gmake install_c This should recompile the c-code using the new Makefile. ...

... The choice of the spectrograph design (Fig.2) is determined by the quantity R, the overall dimensions of the PF cage and the restrictions on the rigidity of the structure of the device. ... As the camera's objective a fast 4-lens aplanat is used having a focal distance F cam =140 mm and a relative aperture of 1:1.8, the resolution at the centre is no less than 80 gr/mm, that over the field at a distance of 3 mm from the edge along the frame ( ) diagonal is 35 gr/mm. ...

Eclipses on Mars . Mars has two moons, Phobos and Deimos . ... They are also much closer to Mars than the Moon is to the Earth. ... These phenomena are particularly sensitive to observer location on the surface. ... In context: The Beagle 2 mission . An experiment of this kind will be attempted early in 2004 by instruments on the Beagle 2 lander. ... It should be noted that Phobos itself can be eclipsed by Mars (a phenomenon analogous to lunar eclipses on Earth) and does so almost every night. ...

... We have started a programme of observations of nearby starburst and AGN galaxies with MICHELLE, with the aim of investigating the spatial extent of "Unidentified Infrared Bands (UIB)" emission in these galaxies, and in particular relating these to multi-frequency matched resolution radio maps. ...
