Abstract:
Science Verification (SV) observations on UT1 have taken place as planned from August 17 to September 1 (cf. The Messenger, 92, 5, for a presentation of the goals and the strategy of SV). Although the meteorological conditions on Paranal have been definitely below average, very valuable data have been gathered and are now being prepared for public release.

Abstract:
The purpose of this document is to provide an overview of the VLT cost evolution since 1987, and an estimate as of to-date of the total cost of this project at ESO until the completion of the VLT/VLTI in 2003. The total cost we quote includes the external contractual costs, the internal labour and other costs directly VLTrelated, the development of the Paranal Observatory and its operations until 2003. This is the date that will see the completion of all 8-metre telescopes, the auxiliary telescopes and all approved instrumentation. It does not include the manpower costs at member state institutes contributing to the instrumentation programme.

Abstract:
Over the past years, a significant effort has been put in verifying and improving the capability of the VLT Unit Telescope (UT) to reach the very demanding Optical Path Length (OPL) stability at the nanometer level, as required by the VLT Interferometer (VLTI). Up to now, this has been done primarily by analysis using detailed Finite Element Models with inputs from dedicated measurement campaigns such as the characterisation of micro-seismic activity at Paranal [1], [2], vibration tests on IR instruments closed-cycle coolers and pumps [3], as well as tests at subsystem level on the M2 unit, on the enclosure, on the telescope structure equipped with dummy mirrors, etc. [4].

Abstract:
The company AMOS (Liège, Belgium) has been awarded, last June, an ESO contract for the delivery of the Auxiliary Telescopes (ATs) of the Very Large Telescope Interferometer (VLTI). Each of these telescopes has a main mirror of 1.8-metre diameter. They move on rail tracks on the top of the Paranal mountain. Together with the main 8.2-m VLT Unit Telescopes (UTs), they will ensure that the VLTI will have unequalled sensitivity and image sharpness that will allow front-line astronomical observations.

Abstract:
In November 1995, the La Silla 2000 working group of the Scientific Technical Committee (STC) as well as the Observing Programmes Committee (OPC) identified a very strong demand by the ESO community for wide-field imaging (0.5–2 degrees) capabilities (cf. Andersen, J. 1996: The Messenger, No. 83, p. 48). In all major areas of research, the primary driver was the identification and preselection of candidate targets for more in-depth studies with the VLT (see also: Renzini, A. 1998: The Messenger, No. 91, p. 54). The OPC report remarked: In any case, an array of CCDs of 8000 ´ 8000 will have to be constructed: This is feasible but will not be a small undertaking.

Abstract:
As the reader will notice, the “News from the NTT” are back in the La Silla News Page, marking the end of the “Big Bang” era (this major upgrade has been described in The Messenger Nos. 75–91). The NTT is now fully returned to the La Silla Observatory. With this, another era is finishing too: Gautier Mathys has left the Team. After 5 years at the NTT (i.e. since the beginning of the team itself), many of these as local representative of the Team Leader, and the last year as Team Leader, Gautier is now preparing the scientific operation of the VLT UT1 at Paranal. His excellent leadership, and his extensive, boundless and all-encompassing knowledge of the NTT systems will be missed by the Team. Since the 1st of August, the author has taken over the duties of NTT Team Leader; he will aim at continuing Gautier’s work to improve the reliability and user-friendliness of the Telescope, while maintaining the full compatibility with the VLT environments

Abstract:
During two months of technical time in July and August, major steps in the 3.6- m telescope upgrade plan were successfully passed. I shortly recall the objectives for the 3.6-m upgrade project (see The Messenger 85, 1996, p. 9): (i) optimisation of the mechanical and optical performance to improve the image quality (IQ), (ii) operational stability and efficiency to minimise downtime and maximise scientific return, and (iii) offer competitive instrumentation. After the upgrade, the 3.6-m telescope will return to the forefront of 4-m-class telescopes in the beginning of the next century.

Abstract:
Due to the slow evolution of some astrophysical phenomena, long-term preservation of observations has always been a major concern of observatories around the world. Be it hand-drawings on paper or 19th-century glass-plate photographs, the issue at stake is how to best preserve data for the future generations.

Abstract:
The analysis of Hubble Space Telescope (HST) engineering telemetry at STScI is a process that evolved over time since launch in April 1990. Today a jitter file is computed for every dataset by a system called Observatory Monitoring System (OMS). The jitter files, produced to study the telescope pointing stability and the trends in the telescope/instrument performance within the orbital environment, are available for datasets taken after October 1994. These files are supposed to contain sufficient information for an astronomer to properly reduce scientific data.

Abstract:
There are a number of motivations for scanning and cataloguing photographic plates: first of all, the release of a 2-billion-object catalogue would generate uncountable science and missionsupport projects which would be more than welcome for HST and future space missions as well as ground-based telescopes. The significance of this project has already been acknowledged with the formation of an international consortium to proceed with its construction with currently available resources. These partners include STScI, CRA (Osservatorio di Torino), ESO and GEMINI. Additional support for the digitisation of the plates (DSS-II) is also being received from ESO, CDS, CADC, NAOJ and the AAO.

Abstract:
In order to facilitate archive data selection and basic data analysis, a number of Java Applets only requiring a common web browser are now complementing the HST Archive [3]. This article discusses various applets which are already part of the archive web interface. These applets display and manipulate FITS images as well as spectra taken with HST. A generic plot utility is also used to present a set of pointing and specialised engineering data, called jitter files [4].

Abstract:
HST science data are automatically calibrated when they are received at STScI (Space Telescope Science Institute) and these calibrated data are included in Baltimore’s archive. The calibration software, which is contained in the IRAF/ STSDAS hst_calib package, takes as input the raw data and any necessary calibration reference images or tables if they are already available [2]. The software determines which calibration steps to perform by checking the values of the calibration switches in the header. It selects which reference files to use in the calibration by examining the reference file keywords. The values of these switches and keywords depend upon the exact configuration of the instrument, the date of the observation and any other constraints. The values are set in the headers of the raw data in OPUS (OSSPODPS Unify System).

Abstract:
The VLT era is rapidly approaching: the first instruments, ISAAC and FORS at UT1, will be available by the year 1999. Indeed, the beginning of the new millennium will witness fierce competition among quite a few 8-m telescopes, operated by different groups. As a consequence, there is a strong need to prepare, in a timely manner, suitable targetlists for the VLT, in order for it to play the leading role in ground-based optical and IR astronomy in the next decade. Preparation is one of the keys to success for the VLT observations.

Abstract:
At the time of their birth, young massive stars are deeply embedded in the dense molecular cores from which they form, thus making it impossible for us to observe them directly. The very early stages of massive star formation can therefore only be detected indirectly through the effects they have on the surrounding cloud via massive bipolar outflows, enhancements of certain molecular species, or infrared emission from heated dust grains.

Abstract:
The 30 Doradus region contains luminous clusters of massive young stars emitting intense UV radiation and powerful stellar winds which have created loops and shells of ionised gas, and shows evidence for a highly efficient formation mechanism unmatched in Galactic molecular clouds. The authors summarise here the results of an ongoing investigation of the characteristics of the highly excited molecular gas and cold molecular gas toward the centre of the 30 Doradus region, made through observations of H2 and CO(2→1) line emission, respectively.

Investments in observational facilities on a European scale, whether on a VLT or LSA scale or in telescopes of more modest size, must be based on careful medium- and long-term planning. As scientific priorities and external conditions (e.g. budgets!) change, so the plans must be revised periodically.

Abstract:
The 6th ESO/OHP Summer School was hosted again at the Observatoire de Haute-Provence (OHP) from 15 to 25 July 1998. The school, held only every second years, selects 18 of Europe’s most promising young doctoral students in astronomy. Courses of lectures, observations, and analysis form the intellectual menu which is aimed at teaching the process of extracting astrophysically digestible results from the photons harvested at the telescopes, such as the ESO VLT, whose four telescopes will become available to the community in turn during the next few years.

Abstract:
There are many links between the Sea and the Space surrounding us. Indeed, Space itself is often likened with a new and uncharted Ocean on which we now continue the great voyages of discovery of the past. Space-based satellites allow us to study the processes in the Earth’s oceans in unprecedented detail and at the same time to verify complex principles in fundamental sciences like physics, chemistry and mathematics. Space is also our tenuous link to the distant places from where the ingredients of life first came to our planet, and the ocean is where they began the incredible evolutionary processes of which we ourselves are a product.
