Subject:	SGP/MFRSR/E11 - 500nm channel intermittently bad
DataStreams:	sgpmfrsrE11.a0, sgpmfrsrlangplotE11.c1, sgpmfrsrE11.b1, sgpmfrsrlangleyE11.c1
Description:	The 500nm channel began having sporadic problems in Dec 2007 and failed completely on 3/30/2008. The instrument was pulled from service on 4/25/2008 for repair. When channel 500 was reporting, the data appear to be OK. However, be aware that it was having problems and there may be subtle problems not identified.
