... 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. ...

... In order to compare the number of different evolutionary stages obtained and X-ray luminosity of the chosen X-ray sources with the observed galactic values we use the sum of C/O+O/C , where C and O are the calculated and observed values of a given binary type, respectively. If we make comparison for a number of different binary species (for example, we compare the number of CV, number of X-ray pulsars,   total X-ray luminosity of LMXB, etc.), we write this criterion in the form: . ...

We investigate models for main-sequence and horizontal-branch (HB) stars constructed using the Carson opacities and make comparisons with models based on the Cox-Stewart opacities. ... The drop in the hydrogen-shell luminosity due to the helium-core expansion during HB evolution is greater than that obtained with the Cox-Stewart opacities. ... Studies of main-sequence (MS) stars lead to agreement with Stothers' (1974a,b, 1976) results for homogeneous models constructed with Carson opacities. ...

PERFORMANCE COMPARISION OF KODAK DCS460 DIGITAL CAMERA AND PIXELVISION BACK-ILLUMINATED CCD . ... ABSTRACT : A Kodak DCS460 digital camera (with 1300 x 1000, 9-micron square pixels) and a PixelVision, back-illuminated digital CCD camera (with 1024 x 1024 elements, 12-micron square pixels) were tested at calibrated light levels ranging from 10 -2 footcandles to 10 -5 footcandles. The PixelVision back-illuminated CCD was shown to be 10,000 more sensitive than the Kodak DCS460 CCD camera. ...
