Proposal Abstract

We propose to observe two radio sources (0400+258 and 0738+313) with HALCA at 1.6 GHz and 4.85 GHz. Both objects are GPS-like radio sources with an unusually wide frequency interval (between 0.4 and 8 GHz) of approximately constant flux density. The high angular resolution provided by HALCA is very important for understanding whether the observed spectra of the sources reflect the contribution of several compact synchrotron self-absorbed components or if we are dealing with a complex structure of free-free absorbing gas in the immediate vicinity of their cores and jets.

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.
