Purpose
=======
Astrometric observations to strenghten the ICRF in the Southern
Hemisphere.
Schedule
========
This is a new schedule generated by Alan Fey using sked.
Correlation
===========
This experiment will be correlated at the WACO Correlator. Data should
be shipped to Washington, DC as soon after the experiment as practical.
Special procedures
==================
None
