Subject:	GRW/MFRSR/M1 - Minor shadowband misalignment
DataStreams:	grwmfrsrM1.b1, grwmfrsrM1.a0
Description:	A minor shading problem affected the morning hours (sunrise - 0930 UTC). Maintenance on 20090709 resolved the problem.

Subject:	GRW/WACR/M1 - Coherence Filter Contamination
DataStreams:	grwwacrM1.b1
Description:	The coherence filter (software) that was added to the WACR under BCR-01500 was causing occasional contamination to WACR data. This was exhibited in the first 2000 m of range by streaking in the data over a period of time. It didn't occur often and when it did, it is quite obvious looking at the plots. On 4/2/2010 at 12:00 UTC, the coherence filter was modified to preclude working on signals with a SNR greater than 60 dB. The vendor thinks this will solve the problem.
