... The properties of the dust grains (e.g., temperature and mass) can be derived from fitting far-IR SEDs (т??100 ЮМm). Only with SPIRE on Herschel has it been possible to get high spatial resolution at 200 to 500 ЮМm that is beyond the peak (~160 ЮМm) of dust emission in most galaxies. Aims: We investigate the differences in the fitted dust temperatures and masses determined using only 200 ЮМm data is for deriving these dust properties. ...

... Keywords: Proper Motions, Schmidt Plates, Astrometry, Guide Star Catalog, Palomar Sky Survey . In this paper we describe a program of determining proper motions from digitized scans of 1950's-era Palomar Sky Survey (POSS) Schmidt Plates and 1980's-era Palomar Oschin Schmidt `Quick V' plates that were taken for the Hubble Space Telescope ( HST ) Guide Star Catalogue. ...

... 2009: . ... New Wolf-Rayet Type Star. ... It was discovered that the peculiar velocity of the star is about 50km/s, and that it was discarded from a young star cluster. ... Based on the observational data from the 6-m telescope and from other sources, it was shown with high reliability that chemically peculiar stars with strong depressions in their continuum energy distributions possess the magnetic fields and rotation periods 2 and 3 times larger, respectively, than the stars with weak depressions....

Categories: calibration GpNorm is a MIRIAD task which corrects gains and polarisation leakage tables for XYphase and leakage offsets. ... GpNorm compares the leakage terms with nominally correct terms, and determines an leakage and XY phase offset to add which will minimise the difference between the two sets of leakages. ... No default. Key: cal The data-set containing the nominally correct leakage table. ...

Some applications of stochastic processes in astrophysics especially in accreting systems were discussed in Lipunov (1987),Hoshino Takeshima (1993) and Lipunov (1992).In Hoshino Takeshima (1993) the authors, using simple models of MHD turbulence, try to explain aperiodic changes in X-ray luminosity of X-ray pulsars. ...

Next: Reduction procedure Up: Extinction and transformation Previous: Strategy . Standard stars can be included in the extinction solution, if one is careful. The problem is that there are usually appreciable ``conformity errors'' due to mismatch between the instrumental and the standard passbands [ 16 ]. ... Thus, it is wrong to assume that the transformation between the instrumental system and the standard system is exact, even if there were no measurement error in either system [ 1 ]. ...

STANDART (ZONE) TIME is a medium solar time, determined for the 24 general geographical meridians, being 15* in longitude. The Earth surface is divided into 24 hour zones (with numbers from 0 to 23) where zone time coincides with the time of the prime meridian passing through these zones. ... The zone time of some zones has it’s own name, for example the zone time of the zero zone is called West – European (universal); the zone time of the second zone is called East-European. ...

The azimuth encoder rack gear is mounted on the inside of the azimuth ring girder. The azimuth encoder turns on this gear as the azimuth moves 0 to 720 degrees. ... The software assumes that this arc length along the encoder rack gear is correct (at a constant radius of 127/2 feet). The error in the radius of the rack gear becomes an azimuth error. To measure the error in the azimuth encoder rack gear, jon hagen built a proximity sensor. ... To compute the az encoder runout error: . ...

... Determining the nominal roll angle for stable intervals . ... We found the necessary information in a file 'rh*.ao', which has a binary extension table for each obi. ... Unlike the question of determining the nominal roll angle, we know of no a priori indication of this problem (although the guide star configuration may be the cause, or at least associated with this condition): it is necessary to examine the source position for each obi. ... The guide star record is at the end of the 'anc file'. ...

... They were determined as a result of orbit improving on the base of all kinds of optical observations available in the catalog of observations of the Minor Planet Center on March 16, 2014 (radar observations have not been used at this stage). ... As the MPC orbits do not all were improved simultaneously with EMP orbits, only 383866 sets of elements were used for data comparison (for selected sets of elements process of improvement had started with the use of the same observations). ...

The small variations in distance to the individual Cepheid variable stars in the Cloud are negligible compared with the much larger distance to the SMC. ... In this way Cepheid variable stars can be used as one of the 'standard candles' in the Universe that act either as distance indicators themselves or can be used to calibrate (or set the zero point for) other distance indicators. ...

Our goal is to determine the orbit of Mizar A. We have reduced, calibrated, and imaged a single night of data which should enable us to determine the separation and position angle of Mizar on that night. The image provides a good guess as to these numbers, but we like to improve them by modeling. In the course of that, we also determine the magnitude differences between the component stars of Mizar. With the results from other night's data we will be able to determine the orbital elements. Continue
