Subject:
NSA/MMCR/C1/C2 - Wrong Polarization
DataStreams:nsammcrmomC1.00, nsammcrspecmomC1.a0, nsammcrmomC1.b1
Description:
The new antenna was mistakingly set to transmit/receive in circular polarization instead 
of linear polarization.  The result is that reflectivities are much lower than they should 
be.  Since we only measure on polarization channel, there is no way to apply a 
correction to go from circular to linear polarization.
Suggestions: 
Do not use the data.
