Subject:	NSA/MMCR/C1 - Reprocess: Antenna Gain Error
DataStreams:	nsammcrmomC1.b1, nsammcrspecmomC1.a0
Description:	The antenna gain used in the calibration table was for the old antenna (54.3 dBi). The new gain figure was received today and it is 52 dBi. The antenna designer stated that the gain has an unexpected and unexplained minimum at the design frequency (34.86 GHz.)
Measurements:	nsammcrmomC1.b1: Cloud, reflectivity, at altitude(Reflectivity) nsammcrspecmomC1.a0: Cloud, reflectivity, at altitude(Reflectivity)

Subject:	NSA/MMCR/C1/C2 - Wrong Polarization
DataStreams:	nsammcrmomC1.00, nsammcrmomC1.b1, nsammcrspecmomC1.a0
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.
