Session Notes for rd0904
Prepared by J. Gipson, NVI, Inc./GSFC


===========================================================
PURPOSE AND GENERAL NOTES 
===========================================================

The purpose of this rd0901 is to determine the positions of some
sources that do not have good positions.  This is in preparation for 
the next version of the ICRF, which is used in geodesy and astrometry.
Many of these sources are very weak. Because of this, the integration 
time is long, and the number of observations is lower than normal.

This session must be recorded on Mk5 disks.
