... About ATNF overview . ... Both are consistent with earlier estimates, computed for the population of optically selected galaxies. This consistency occurs because, although the distribution of optical central surface brightnesses among galaxies is flat, we fail to find a population of galaxies with central surface brightnesses fainter than 24б  B - , even though there is no observational selection against them. Keywords: Galaxies: Luminosity Function, Mass Function; Surveys . ...

The original files with the data were in different formats. ... Such files were named "standard data files" and linked to the database. They can be easily transformed to any desirable format by a code. Here we present two simple computer programs of this kind. ... When running the code, you can specify columns in the output file: wavelength, energy (eV) or wavenumber (cm -1 ) as the first column, and complex refractive index or dielectric function as the second and third columns. ...

Next: Selecting the backup tool Up: Backups Previous: On the importance of . The most important decision regarding backups is the choice of backup medium. ... Cost is important, since you should preferably have several times more backup storage than what you need for the data. A cheap medium is usually a must. ... A hard disk is typically very reliable, but as a backup medium it is not very reliable, if it is in the same computer as the disk you are backing up. ...

... This step is done mostly interactively and uses some basic ad-hoc IDL procedures, mainly for testing and checking of the consistency of the results.Once the observations have been selected and the count spectra extracted, the available spectra of each background level are accumulated. ... Average QUALITY such that QUALITY =0|1 Exposure times are added and the total is written in the EXPOSURE keyword of the header of the output FITS file. Finally, the CCFs are built from these templates. ...

Next: Stars Up: Calibrate data Previous: Unwrapping triple phases Contents . The C ALIBRATE A STROMETRY menu allows you to solve for station coordinates (and star positions) using the delay data. Use P LOT to plot the O-C data. Select input beams higher than one, since delays are referenced to the delay in input beam one.) ... If no star is selected, then no star position will be solved for, but data of all stars will be used for the station coordinate solution. ...

... The numbers of three types of compact binaries containing accreting NSs and BHs, which are most interesting from the point of view of their observational appearances, have been calculated as a function of time: i) X-ray transient source containing a NS in an eccentric orbit around a main sequence Be-star (the observed prototype: A0535+26), ii) BH The evolution of the selected types of X-ray binaries during the first 10 million years after the starburst onset is presented in Fig. ...

... 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. ... Arrows indicate the magnitude and direction of the proper motion for the stars. ...
