Proposal Abstract

The AO2 phase of the VSOP mission is a very favorable period for observing sources which lie close to the south ecliptic pole. This is because the current orbit evolution and sun angle constraints of the HALCA spacecraft allow sources within 10^{\circ} of the south ecliptic pole to be continuously observed with good u-v coverage. The source PKS 0637-752 (J0635-7516) is ideally located to take advantage of these constraints and conditions. It is also a quasar with strong, flat-spectrum radio emission, a marginally resolved core, and a strong mas-scale jet. Hence, it is one of the few sources in the sky that is suitable for extended monitoring with the VSOP mission. We propose observations of PKS 0637-752 at 4 epochs, spaced at 4 month intervals, over the AO2 period from 1998 November to 1999 December, at 5 GHz. We request each observation to be of 2 days (8 orbits) duration in order to maximise the u-v coverages.

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.
