Total number of observations (delay measurements): 1341
Total number of scans in the schedule: 162

Purpose
=======
Astrometric observations to strenghten the ICRF in the Southern
Hemisphere.

Schedule
========
This is a new schedule generated by Alan Fey using sked.

Correlation
===========
Data should be shipped to the correlator as soon after the experiment
as practical.

Special procedures
==================
None
