Total number of observations (delay measurements): 1850
Total number of scans in the schedule: 144

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
