SGP/MWR/B4 - New software version (4.15) installed
DataStreams:sgpmwrlosB4.b1, sgpmwrtipB4.a1
Description:
A problem began with the installation of MWR.EXE version 4.12 in July 2002. The software 
had been upgraded from a "DOS" to a "Windows"-compiled program to address an earlier 
problem.  The software upgrade corrected the earlier problem but introduced a new one that 
caused line-of-sight observing cycles to be skipped, a 15% reduction in the number of tip 
curves, and saturation of CPU usage. Software versions 4.13 and 4.14 also produced these 
problems.

The new MWR software, version 4.15, was installed on 9/13/2005. As a consequence of this 
upgrade, the tip curve frequency increased. The tip cycle time decreased from ~60s to ~50s.

SGP/MWR/B4 - computer problem
DataStreams:sgpmwrlosB4.b1, sgpmwrtipB4.a1
Description:
The Dell computer motherboard failed. The instrument was taken off line and a motherboard 
replacement was ordered.

On 10/07 the new motherboard was installed, data have been consistently good since the 
installation.
