The seminar is supported by the grant of Federal Programm "Integration" . annotation of talk . A.V. Kuznetsov (IKI) . The Catalog of the GRB Sources . The catalog of the GRB sources is composed on the base of BATSE data up to 01.08.99. This catalog includes about 90 candidates determined by the GRB ckusters. ... The tables with basic data of the GRB clusters and the sources are pesented. ... Practically the present work is an attempt of the GRB source catalog creation. ...

... Actor Prolog supports so-called repeated proving of sub-goals. ... Logical actors are a name of these repeatedly proved sub-goals. ... A logic program consists of sub-goals that must be proven in the course of an execution of the program (like a usual imperative program consists of commands to be executed). ... There are some logical actors in the outside world from the standpoint of the ideology of Actor Prolog , and a program interacts with these external actors. ...

Next: Identification loop Up: Wavelength Calibration Previous: The Echelle Relation . As a consequence of the cross-disperser dispersion relation, a given line repeated in two overlapped regions of the spectrum must be found at the same y position if spectrum and detector are perfectly aligned. ... The above condition provides a geometrical way to estimate the angle, as: , with the difference in y position of the two occurences of the pairs and the difference of their x positions. ...

... I enrolled in his "zero-hour" research class early in the morning [see Black Holes to Blackboards, September/October 1995, p. 8]. Peering at a sheet of vellum over a map of the martian surface, circling and measuring craters for hours, I learned that science isn't all fun and games. ... It was a dream come true: to be surrounded by other young people who were interested in astronomy, to be taught by professional astronomers, and best of all, to use large telescopes. ...

Experiment COLD . ... Statement of the Problem . The observer must resign himself to the fact that it is senseless to attempt to actually attain the potential sensitivity of modern radio telescopes without ever using any a priori information about the object being studied and extremely careful study of the properties of all kinds of additional sources of noise. ... The problem in Experiment Cold were formulated in just this way. ... A List of the Problems Studied in the Deep-Survey Cycles . ...

... Connecting the planned observations and the actual status of the Chandra X-ray Observatory is the observation interval determination pipeline ( OBIDET ). This collection of tools allows the Chandra X-Ray Center Data System automated processing to process the data through the necessary pipelines based on what was actually observed. ... In the case of the Chandra X-ray Observatory, the observation interval determination pipeline ( OBIDET ) is used for this task. ...
