Astrometric global solution 2004f_astro used all available VLBI observations including 15 observing sessions of the VLBA Calibrator Survey at 8.4GHz and 2.2 GHz from 1979.08.03 to 2004.11.23, 3892 diurnal sessions, 4,759,337 measurements of group delays.

Positions of 2658 sources were adjusted in a single least square solution. Currenly, this is the most complete catalogue of positions of compact radio sources. Technical description of the solution is available here.

Results

1. 2004f_astro catalogue in HTML form (5 Mb). The catalogue contains source positions, their uncertainties, estimates of the total VLBA flux density, the VLBA flux density of unresolved components, naturally weighted CLEAN images in postscript and in fits format at X and S-band; plots of the correlated flux density as a function of the length of the baseline projection to the source plane; fits files with calibrated uv data. NB: so far images and fluxes are available only for 725 sources observed in VCS2 and VCS3 campaigns.
2. 2004f_astro catalogue in ASCII format. The catalogue contains source positions, their uncertainties, total VLBA flux density, the VLBA flux density of unresolved components.
3. 2004f_astro catalogue in blokq format. The catalogue contains source positions and their uncertainties. This catalogue can be used as a priori file for Mark5 VLBI analysis sofware package Calc/Solve
4. Images and uv data of 725 sources in one tar.bz2 file (481Mb). Refer to the readme file for the file name convention in this archive. These images were obtained from processing 5 VCS2 and VCS3 observing sessions.
