Proposal Abstract

We wish to make VSOP observations of the ``new'' radio source 1308+328, which is unresolved on Earth baselines at 8.4 GHz. Measurements at 1.6, 5 and 22 GHz of angular size, or upper limits, together with the observed X-ray emission, will constrain the parameters of the relativistic effects which affect the observed emission. At 1.6 GHz both 1308+328 and the nearby strong compact source 1308+326 (14' away) are within the VSOP primary beam. By switching rapidly between these two sources with GRTs, we hope to be able to "connect" the GRT-VSOP visibility phase as a function of time. Although a priori errors in the VSOP position probably exclude a direct use of this to determine an accurate source separation, it will furnish data for investigating the limits of such space-VLBI astrometry.

The full Cover Sheets (compressed post-script, typically 50kbytes) can be retrieved. Note that many 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 AO1 proposals were submitted in November 1995, and information such as affiliations and contact details has changed for some proposers since that time. The Cover Sheets (and the details on this page, which were derived from the Cover Sheets) may therefore have changed.
