... The HST uses an onboard model of its orbit to perform in real-time various control functions relating to spacecraft operations and observation support. ... New coefficients for the ephemeris are updated every other day, and are archived as FITS keywords for each HST observation data set. Using these coefficients,an observer can perform a variety of calibration and characterization calculations relating to the orbital position and velocity of the telescope. ...

Electronic Catalogue of Comets "Halley" . ... In this paper we give a description of the Electronic Catalogue of Comets "Halley", which makes it possible to calculate the evolution of the orbits of comets, to visualize orbital motion, to determine the circumstances of a comet's close approach to planets within a given time interval, as well as a number of other opportunities. ...

... The hydrogen line is the most pronounced absorption feature in spectra of B-type stars. Two effects play the dominant role in observed behavior of : the Stark broadening of the line absorption coefficient and interstellar absorption. ... Keywords: B-type stars, H I line, Stark effect, interstellar absorption . ... Thus having a good description of the Stark effect we investigated early B-type stars, where interstellar absorption may play an important role. ... 4 (IUE observations) and Fig. ...

... All the optical elements are mounted in a cryostat aimed at keeping components at a temperature of about 80 K. The focal plane masks (field stops or slits) are mounted on a wheel. ... The collimator is an achromatic doublet lens, which images the entrance pupil of the TNG and provides an almost parallel beam (F-number about 2000) at the pupil plane, where Lyot stops can be placed. Right after the pupil plane, two close wheels mount filters and grisms. ...
