Next: Acknowledgements Up: PEPSYS general photometry Previous: Maximum limits . ... This special system tape was labelled PEPSYS (for Photo-Electric Photometry SYStem). ... The Manfroid -- Heck program [ 15 ], and a program used at that time by Peter Stetson were investigated, but found to be too specialized to particular photometric systems and data formats to be generally useful, so a proposal was made to NSF to develop something along the lines of the present system. ...

... The routine processing of STIS data in the calibration ``pipeline" requires an interrelated set of software tasks and databases developed and maintained by many groups at STScI. We present the systems-level design of this calibration pipeline from the perspective of the STIS instrument group at STScI. We describe the multiple interfaces to the pipeline processes that the STIS group works across in an effort to provide for the routine calibration of STIS data. ... For example, the STIS group: . ...

... In order to realize the optimal scientific return from the VLT, ESO has undertaken to develop an end-to-end data flow system from proposal entry to science archive. The VLT Data Flow System (DFS) is being designed and implemented by the DFS Group (ESO Internal access only) in collaboration with VLT Division and Instrumentation Division . ... VLT Control System Interface . ... OBs are the quantum of data that flows within the DFS, collecting state, data and status information as they flow. ...

Next: Recording Systems Control Up: Recording Systems. ... SCHED was originally written in about 1979 as the scheduling program for global VLBI observations using the Mark II recording system. That was a system capable of recording 4 Mbps on video tape recorders. ... The wide band recording system in use for VLBI for many years was the Mark III system. ... However, SCHED was capable of scheduling Mark III observations on systems that used the VLBA control files (VLBA, VLA, and Green Bank). ...

The XPA messaging system provides seamless communication between many kinds of Unix programs, including X programs and Tcl/Tk programs. It also provides an easy way for users to communicate with these XPA-enabled programs by executing XPA client commands in the shell or by utilizing such commands in scripts. ... A program becomes an XPA-enabled server by defining named points of public access through which data and commands can be exchanged with other client programs (and users). ...

... Search system . ... Forget-Me-Not" information and searching system is developed to store and to work with unstructured fascimile electronic copies of paper documents (e.g., books, newspapers, incoming and outcoming business documents, etc.) as well as text documents in Windows 95/98/NT environment. ... Incoming text documents are converted by means of the Box Manager, which is a part of the "Forget-Me-Not" information system, into a dynamic archive - a storage of the text information images. ...

The conference program included eleven one-hour talks and four free discussions. ... The talk also discussed different models for Internet traffic and quality of Service measures. ... The talk by Nikolai Vereschagin (Moscow State University) "The Kolmogorov complexity of approximate descriptions" discussed different notions of descriptive complexity of computable sequences which can be used in Internet measurements. ... What mathematics does Internet need?" ...

Next: Binary Radiopulsars with Black Up: Black Holes in Binaries Previous: Black Holes in Binaries . Two different types of stellar BH formation exist: (1) direct core collapse   of a massive star and (2) AIC of a NS. A BH of the first type presumably will have a mass comparable to that of the collapsing star and can be born both from a single star and in a binary system. ...

Next: Mail Up: Major services in a Previous: Network logins . One of the more useful things that can be done with networking services is sharing files via a network file system . The one usually used is called the Network File System, or NFS, developed by Sun. With a network file system any file operations done by a program on one machine are sent over the network to another computer. ... This makes information sharing extremely simple, since it requires no modifications to programs. ...

Databases for Observations and Orbit Elements for Asteroids and Comets in ERA System . ... In the present paper the databases for both observations and elements of asteroids and comets in the ERA system are described, as well as examples of the orbit determination and the processing of observations for these objects. The peculiarities of computations are described and examles of usage of the ERA system for orbit determination are presented. ...

... Using UNIX System Calls and Library Functions . ... To use system calls and library functions in a C program we simply call the appropriate C function. Examples of standard library functions we have met include the higher level I/O functions -- fprintf() , malloc() .. ... For most system calls and library functions we have to include an appropriate header file. e.g. stdio.h, math.h . ... Information on nearly all system calls and library functions is available in manual pages. ...
