Beginning with day 094 (Apr 04), we include data from PRN06/GPS36, launched on
day 069 (Mar 10).  Additionally, according to the file nanu1994.mes obtained
from the IGS CBIS, this satellite is scheduled unusable from day 099 (Apr 9)
14:56 UT until day 102 (Apr 12) at 16:00 UT for repositioning.  We have
excluded all data from this satellite for day 099. 

The inclusion of data from FORT caused an excessive number of outliers in the
analysis of day 096 (Apr 06). We have deleted this site from our processing for
this day.

This week's analysis includes the processing of data from a new station, CHTP
(Chatsworth, CA, USA).  The following nominal coordinates were assumed, and the
station locations were estimated (unconstrained) each day:

    X = -2529823.4990 m,   Y = -4632010.2080 m,    Z =  3570394.1760 m

WARNING: Data from FORT have been excluded for day 096.
WARNING: Data from PRN06 have been excluded for day 099 due to a maneuver.
WARNING: Little data from PRN03 on days 098,099; PRN13 on day 098.
