Proposal Abstract

We propose VSOP phase-referencing observations of the source pair 3C 66B and 3C 66A. Since the sources are so close, i.e., separation angle is 6.4 arcmin, that they can be observed simultaneously within the primary beams of the HALCA and that of VLBA antenna, atmospheric phase fluctuation can be removed during all observing time. Therefore, we will able to measure precise proper motions of the pc-scale radio jets and inner motion of the core region. These data will be highly useful in revealing the oribital motion of the binary black hole.

The full Cover Sheets (compressed post-script, typically 50kbytes) can be retrieved. Note that some proposals were reduced in extent by the Scientific Review Committee (e.g. by reducing the number of experiments), however the Cover Sheets contain the full proposal as submitted. Also note that AO4 proposals were submitted in October 2000, and information such as affiliations and contact details has changed for some proposers since that time.
