The Database of Close Binary Systems . ... Team . ... This web-based interactive database is being developed and maintained by a team at the Sternberg Astronomical Institute of the Moscow State University . The project is an on-line extension of our catalogue on "Highly Evolved Close Binary Stars" (volumes I, II) published by Gordon and Breach in 1996. As of September 2009, the database (both the software and the content) is in its development/testing phase. ...

... The Science Operation Department is composed of Astronomers, Telescope Instruments Operators(TIOs) and Data Handling Administrators(DHAs). ... Astronomers have proposed several methods to quantitatively measure the amount of turbulence above the telescope, which the most common ones is Differential Image Motion Monitor (DIMM). In optical testing, the Hartmann test is the common method to test the quality of optical components. ... Hartmann mask consists of 48 lenses. ...

... Cost­E#ective System Management Skip Schaller Steward Observatory, University of Arizona, Tucson, AZ 85721 Abstract. Quality system management of computer workstations for as­ tronomy can be achieved with relatively small manpower requirements, if the right cost­e#ective administrative design decisions are made. ... The system is designed so that one doesn't depend on four or more hosts, (such as a software server, cpu server, data file server, font server, etc.) to get work done. ...

In the scalar Helmholtz equation the variables are separated in 11 physically interesting coordinate systems [ 55 ], however for the vector field containing 3 scalar functions, the complete separation of variables is possible only in 6 systems: Cartesian, 3 cylindrical, conical and spherical ones ([ 55 ], Ch.13). Therefore, the formal solution suggested in 1927 by F. Moeglich [ 368 ] for the spheroidal coordinates was practically usefulness until the work of Sh. ...
