	- yes, but that was only for the LASP f/w, and specifically did NOT 
include the SRTM f/w.  We assume therefore that a separate review will 
be needed for the SRTM f/w

        - OK, will take that part out

	- the text includes these statements: "In the meantime, some effort can 
go into further improving and reviewing the design, though this will not 
significantly reduce the time needed later for testing. In addition, 
preparations are continuing to hold the ATLAS Specifications 
Verification Review (SVR) as scheduled on April 24; this work should not 
be impacted significantly by the TW situation."
	- this was to make clear that there is work ongoing, and we are not 
paying "standing army".  However, since the work that can be done is, in 
some sense, "extra" design work that will not reduce the labor needed 
later, there is an overall increase in the labor costs, which is the 
$30k estimate
