Observation of star-forming regions with VERA and the development of CCcoda
-- the fundamental library of the VERA Data Analyzer

The VERA (VLBI Exploration of Radio Astrometry) project is the only <br />
10-micro-arcsec scale astrometry observation running <br />
currently. Observation series in radio wavelength in 22GHz and 43GHz <br />
are performed with 4 radio telescopes in Japan. The aim of VERA is to <br />
measure accurate distances, their proper motions and internal motions <br />
of radio sources in Galactic star-forming regions and late-type stars. <br />
To achieve 10-micro-arcsec accuracy stably the new software with <br />
enough numerical accuracy is needed. VEDA (VERA Data Analyzer) is <br />
under development for this purpose and the fundamental library for <br />
VEDA \"CCcoda\" have been developed. In this seminar current results of <br />
VERA are introduced and the structure of CCcoda is described.
