Total number of observations (delay measurements): 399
Total number of scans in the schedule: 189

Purpose
=======
Astrometric observations to strenghten the ICRF in the Southern
Hemisphere by observing ICRF Candidate sources and less well observed
ICRF Defining sources.

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

Correlation
===========
This experiment will be correlated at the WACO Correlator. Tapes 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) =   6.4
 Min =    .0   Max =   22.1 (Baseline Ho-Ts on 2209+236)   RMS =   4.7

 Total time:       1447 minutes ( 24.1 hours).
