Total number of observations (delay measurements): 1317
Total number of scans in the schedule: 158

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

Summary
=======
The following listing is a summary of the observations in this schedule.


 Average number of obs. per baseline per source(normalized by up-time) =   8.3
 Min =    1.2  Max =   30.5 (Baseline Hh-Ww on 1604-333)   RMS =   5.2
