Historical Celestial Cartography: a Proposal to Improve the Documental Description of the Contents of Star Charts and Atlases

Abstract: A sample of 18th, 19th and 20th-Century historical star atlases from the Royal Institute and Observatory of the Spanish Navy and the Linda Hall Library have been selected in order to identify the most frequently supplied scientific information. This work shows how the quality of bibliographic records could be improved, not only by adding more specialized description fields, but also by ensuring that the existing ones are being properly used by cataloguers. A series of new technical parameters is proposed, along with guidelines on how to find them, thus making the task of identifying such parameters easier for cataloguers.

Use of two traveling GPS receivers for a relative calibration campaign among European laboratories

Abstract: We report about a GPS receiver relative calibration campaign, which took place between five European National Metrology Institutes or Designated Institutes: LNE-SYRTE in Observatoire de Paris (Paris, France), where the reference receiver of the campaign was located, ROA (San Fernando, Spain), SP (Boras, Sweden), PTB (Braunschweig, Germany) and INRIM (Torino, Italy). We used as traveling equipment two main units, both connected to a single antenna, and we kept track of the offset between both traveling units in all the visited sites. An external validation of the resulting hardware delays is provided against the time scale differences derived from the UTC - UTC(k) data published by BIPM in its monthly Circular T. Thanks to a very good stability of the traveling equipment, we obtained expanded uncertainty estimates within 2.0 ns (k = 2) for the hardware delays.

Geodynamical Studies on Deception Island: DECVOL and GEODEC Projects

Abstract: Deception Island (63° S, 60° W) is situated in the South Shetland Islands, and it is the main active volcano in the Bransfield Strait, with recent eruptions in 1842, 1967, 1969 and 1970. Its volcanic and seismic activity has been monitored from 1986 to study the geodynamic activity on the island. In this paper we present the objectives and some results obtained in DECVOL project, a crossdisciplinary study which was planned to evaluate the volcanic status of the island after the crisis occurred during the 1998/1999 campaign, as well as the goals and activities which have been carried out in the framework of GEODEC project, a multidisciplinary project to continue with the studies on the island.

Echo-character of the NW Iberian continental margin and the adjacent abyssal plains

Abstract: The acoustic facies analyses have provided an important basis for sedimentary processes in the deep-sea environments. The echo-character mapping, through the interpretation and correlation of very ...

On calibration of network time services

Abstract: This paper proposes methods for calibration of two network time services—NTP servers and time-stamp authorities. The calibration is described in conformity with metrological principles like other time distribution systems. The authors have built up the calibration sets and tested them in cooperation with five European time and frequency laboratories. The paper also presents and discusses experimental results collected by measurement of time servers between involved laboratories.
