Proposal Abstract

We propose VSOP observations of 3C84 at both L and C bands, at three epochs. Combining these with our complementary VLBA observations at about three times higher frequency will allow us to separate resolution and spectral effects, and extend our knowledge of the brightness distribution, structural variations, and component spectra to finer angular scales. Our scientific goals concentrate on the high-brightness core. We seek to localize the true center of activity, study the spectral index of the core, determine the structure and orientation of the innermost jet regions --- including whether the jet is intrinsically one- or two-sided, and detect motions within the core. Satisfactory (u,v) coverage is available during the AO2 interval, but only within a narrow, four- or five-month time window. We request observations at each frequency at the beginning, middle, and end of this window.

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 AO2 proposals were submitted in May 1998, 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.
