I'm surprised it clipped! To: aseel.anabtawi@jpl.nasa.gov Subject: Re: MGS RST Rpt HEA3219A.TXT Cc: kusza@stanford,joe@neptune,chinsan2 >Max SNR was 65.3, and fgain was 72. I'm surprised it clipped! Actually, it didn't. But it was VERY close. Chinsan has been using 'clipped' to denote danger zone (possible clipping during the diffraction period of an occultation) and 'saturation' when the histogram looks definitely bad. I recommend an increase of 3 dB in fgain over the 72 that you were using. We may be getting into the anomalous SNR/fgain zone that we discovered during the MEX tests - where the noise is so far below the carrier that the algorithm starts to break down. And it will continue to get worse until the end of August. Another subject: Chinsan says he has not received an e-mail for the DSS 65 pass that began on 2003/218 and extended into 219. There have been e-mails for later passes, but this one seems to have gone into the twilight zone.
