In this article we present the Data Flow System (DFS) for the VLT Interferometer (VLTI) that is analogous with that of other telescopes of the VLT. The DFS was first installed for VLTI first fringes utilising the siderostats together with the VINCI instrument and is constantly being upgraded in phase with the VLTI commissioning. A recent VLTI achievement has been the first fringes with the Unit Telescopes (see article on page 1).

ESO's Next Generation Archive System

ADS BibCode:
Telescopes and Instrumentation
Wicenec, A.; Knudstrup, J.; Johnston, S.
Early in July 2001 ESO/DMD installed prototype versions of the archiving and buffering units of the Next Generation Archive System (NGAS) at the 2.2-m telescope in La Silla. The two units are the on-site part of an archive system we are currently testing for high data rate/high data volume instruments like the Wide Field Imager which is mounted at the 2.2-m telescope. The NGAS concept is built around two ideas: the use of cheap magnetic ATA-100 disks as the archiving media and a highly flexible and modular software called NG/AMS, NG Archive Management System. The main goals of the whole system are scalability in terms of data volume, but also the ability to support bulk data processing either by fast data retrieval or by opening the computing power of the archive for data-reduction close to the data themselves. In fact the NGAS scales in such a way that it is possible to process all the data in the archive within an almost constant time. In this article we present an overview of the NGAS concept, the NGAS prototype implementation and some of the experience we have made during the first month of operating the system in a real observational environment. We also present the infrastructure of the main archive which supports scalable, decentralised processing, both of which are essential for large-scale scientific programmes submitted to a Virtual Observatory.

Sterzik, M.
On October 16, the second in the series of the 2001 Topical Meetings at ESO/Vitacura was about “Brown Dwarfs and Planets”. More than 30 participants, the majority being researchers and students based in Chile, discussed the current status and future prospects in this rapidly growing field, a field that was actually pioneered with the discovery of the first free-floating brown dwarf, Kelu-1, in 1997 by the Chilean astronomer M.T. Ruiz. The topic was introduced by a review on the theories of star and planet formation, in the perspective of planet searches (G. Wuechterl).

Ellison, S.
This Topical Meeting was held in Vitacura on October 2–3. The technique of high-resolution spectroscopy is exploited in many areas of astronomy, as was reflected by the breadth of scientific talks given over the two days and the attendance of astronomers and students from universities in Santiago and Concepción as well as several visitors from Europe and other Latin American countries.

Founded as an advisory body to the Director General, the Users Committee mainly works at the interface between ‘common users’ and ESO representatives. This article describes the role of the UC, highlights some of its recent activities, and outlines some areas where the communication between ESO and its users can be improved

Book review: Reflecting telescope optics II, by Ray Wilson

ADS BibCode:
Noethe, L.; Wilson, R.
Volume I appeared in 1996 and was reprinted with significant corrections in 2000. It deals with the historical development of the reflecting telescope with essentially “classical” technology from its invention up to about 1980 and gives the complete optical design and related theory of virtually all known telescope forms. An interesting addition in the reprint is the recently researched identity of Cassegrain in the Portrait Gallery of App. B. Volume II appeared in 1999 and deals with all aspects of the technological “revolution” from about 1970–1980 onwards, which allowed the breakthrough of the absolute barriers to further progress both in size and optical quality imposed by the limitations of classical technology. A corrected reprint appeared in mid- 2001.
