Task: WP6 - Task 2.3 - Calibration of astrometric positions

Leading Institute: University of Bordeaux

Local Leader: P. Charlot

Objective or Use Case: Develop algorithms/observing strategies to combine wide-angle (global) VLBI astrometry with narrow-angle (local) VLBI astrometry, i.e. combine group delays and phases, to produce improved, denser and unified reference frames.

Major milestone: Final report on new algorithms and observing strategies for astrometry - Month 28

Minor milestones: To be developed in the coming weeks. Contributing institutes (total man-months)

   Bordeaux: 21
   JIVE: 3
   UMAN: 3
     NRAO: to be discussed

Platform/strategic choices: Platform not yet defined Applicable to EVN, e-EVN, VLBA, global VLBI, e-MERLIN

Identified manpower: P. Charlot, 1 postdoc (to be hired), S. Garrington, H. van Langevelde (or anyone else from JIVE), E. Fomalont

Any other issues: 11/06/09: matching funds would be granted by the Region (Conseil Regional d'Aquitaine). Will be confirmed in September 2009. 20/07/09: will meet Ed Fomalont in Socorro to discuss the level and details of NRAO involvement 01/09/09: expected start of work

ALBiUS/Bordeaux:

Nb of hours: 26 hours (details: 24 hours for kickoff meeting + 2 other hours for email exchange/preparation of form for previous meeting/issues related to funding for matching time/…)
