Proposal Abstract
We propose to observe two of the four most compact sources studied
at 2.3 GHz in the TDRSS space VLBI experiments: 0420-014 and
1519-273. The purpose is to make accurate measurements of the
brightness temperatures of these sources at both 1.6 and 5 GHz.
By observing with the VLBA on the ground, our calibration accuracy
(due to uniform, well-understood ground antennas, and to the
multiple crossing points available with good u-v coverage) will
be superior to that expected for the VSOP survey. For the most
compact sources, good calibration accuracy on the longest
space-ground baselines is crucial in making accurate brightness
temperature measurements.

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.
