Ongoing Activities:

TAPS:

Trending, Analysis and Plotting System (TAPS) development continues with 
emphasis being placed on fixing the DRs attributed to the current release. 
Testing is progressing on both TAPS#1 and TAPS#2.  Release 4.1.3 was 
installed on 05/27/03 but it has been determined that a re-release is 
required because there were some installation problems on both systems 
(TAPS#1 and TAPS#2).  The re-install should occur on 05/30/03 and will be 
Release 4.1.4.

----------------------------------------------------------------------------
Automation (ROBOTT):

Testing of the Offline and HSM systems is progressing. Testing by the 
Automation team for Command and Control is still paused due to testing at 
WIND. The first release of Command and Control to the FOT is still TBD.
