The BARD dataset has been processed in the ITRF2000 (Altamimi et al., 2002). The solutions (Houlié and Romanowicz, in prep) are in good agreement with campaign solutions (BAVU and USGS) previously released (d'Alessio et al., 2005). The new coordinates release of the BARD network includes the presently operating sites and the velocity of the sites already transferred from BSL to PBO during the last two years.
All the BARD sites have been processed jointly with IGS sites in California. No a priori constraints have been assumed during the processing. All the velocities included in the first release of California Reference Frame (CALREF) are given in Table 3.13. The CALREF will provide velocities and coordinates of sites located in the bay area at specific epochs. Each solution will be associated with error estimations (formal and real). Every surveyor will be able to control the reference site coordinates for a given survey.
