NSA/TSI/C1 - Software problem
DataStreams:nsatsimovieC1.a1, nsatsicldmaskC1.a1
Description:
When the TSI computer was upgraded to a Windows 7 virtual machine, the scheduled task to 
stop the software each day was not configured correctly. Image processing became 
back-logged requiring manual intervention and use of the batch processing feature. This resulted 
in missing cldmask files and out-of-sequence movie files. The scheduled task was corrected.
