Total number of observations (delay measurements): 1850
Total number of scans in the schedule: 145

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

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) =   6.7
 Min =    1.5  Max =   27.7 (Baseline Hh-Ww on 1144-379)   RMS =   4.0
