An analysis of Bordeaux meridian transit circle observations of planets and satellites (1997-2007)
Context. Meridian transit circle observations of the planets and their satellites are regularly performed for ephemerides improvement. Some have been made in Bordeaux observatory during the period 1997-2007. Aims. This paper presents these observations and makes an analysis of the data in order to determine the accuracy of the observations, their interest for dynamical purpose and a comparison ...
متن کاملGlobal reduction with proper motions for meridian observations
When we deal with astrometric observations spread over periods longer than a few years, it is of major importance to take into consideration the proper motions of all objects involved in the reduction process. Not to consider such quantities, mainly when they are poorly known to the majority of the objects, may significantly degrade the final results of the reduction. In this paper, we present ...
متن کاملThe Bordeaux meridian observations of asteroids . First determination of the mass of ( 11 ) Parthenope ?
The asteroid observations made with the automatic meridian circle at Bordeaux observatory from 1985 to 1994, and which have recently become available, are presented. The residuals of these observations obtained using the orbital elements published in the “Ephemerides of Minor Planets for 1996” are analysed. An anomaly for the asteroid (17) Thetis was found, indicating a current close encounter ...
متن کاملThe Parkes Galactic Meridian Survey (PGMS): observations and CMB polarization foreground analysis
We present observations, maps, polarised emission properties study, and CMB foreground analysis of the Parkes Galactic Meridian Survey (PGMS), a project to investigate the Galactic latitude behaviour of the polarized synchrotron emission at 2.3 GHz with the Parkes Radio Telescope. The survey consists of a 5◦ wide strip along the Galactic meridian l = 254◦ extending from the Galactic plane to th...
