Study of the applicability of the curlometer technique with the four Cluster spacecraft in regions close to Earth [PDF]
Annales Geophysicae, 2012 Knowledge of the inner magnetospheric current system (intensity, boundaries, evolution) is one of the key elements for the understanding of the whole magnetospheric current system. In particular, the calculation of the current density and the study of

Image et mesure : deux cultures aux origines de l’astrophysique française
Cahiers François Viète, 2006 In the commission preparing the 1874 transit of Venus, debates about the choice of photographic techniques are illustrative of the stakes that would come to characterize the beginning of astronomy in France over the following decades.

REGAT: A permanent GPS network in Algeria, configuration and first results
Heliyon, 2019 The REGAT (“REseau Géodésique de l'ATlas”) geodetic network is composed of 53 continuously–recording GPS stations distributed in the Algerian Atlas. It spans the whole width of the Algerian coast and reaches 300 km inland, with inter-sites distance of ...

Stark broadening parameter tables for Kr VIII [PDF]
Serbian Astronomical Journal, 1999 Using a semiclassical approach, we have calculated electron−, proton−, and He III−impact line widths and shifts for 6 Kr VIII multiplets as a function of temperature and perturber density.
