2. ADASS 2003 Conference Proceedings
... Previous: Access to Atomic and Molecular Data/Databases in the VO . ... We present the general characteristics of a database for binary and multiple stars from all observational categories, specifically designed to address the awkward topics of the identification of stellar components. BDB is based on a modular architecture to allow the easy integration of data from various sources. We describe in particular the set up of connections with other double star databases through the Internet. ...

4. Terrestrial Silicates Compared to Astronomical Silicates
The silicates that produce the 10 and 18 micron features appear to be broadly similar to terrestrial minerals such as Forsterite and Enstatite. ... Where pre-solar silicate dust grains can be isolated from meteorite material, these also tend to be Mg-rich silicates rather than Fe-rich silicates. ... It has been suggested that the interstellar silicate grains have a different 10 micron feature profile than what is observed for the silicates around evolved stars. ...

If SM can't open TERMCAP as a file, it is taken to be the value of the entry for your terminal. ... A TERMCAP variable takes precedence over an entry in your `.sm' file. ... There is a problem with using the last line of the screen as the SM command line, and this is that some terminals use the same screen for graphics as for text, and your graph will merrily scroll away as you type...

15. Correcting for exposure before smoothing
... Different sections of an image may have different exposure. ... The obvious remedy for this is to divide the input image by the exposure map before smoothing. ... If you wish to create a background map in counts per pixel from an XMM exposure in which the exposure time varies significantly between CCDs, then you will need to remultiply the the output image by the exposure map; if however you wish to create a mosaic from several different cameras or pointings, you may wish not to do so. ...

16. Comparing files
. You can display the line by line difference between two files with the diff command. diff file1 file2 . The information given by the command tells you what changes need to be made for file1 and file2 to match. If there is no difference between the files you are returned to the shell prompt . diff indicates which lines need be added ( a ), deleted ( d ) or changed ( c ). Lines in file1 are identified with a ( < ) symbol: lines in file2 with a ( > ) symbol. Examples . Did You Know? .

18. The COOC Criterion (Criterion of Observations versus Calculations)
... 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: . ...
