The DSP at DSS 65 went red at 15:03, the station said they had to replace a hard disk. They came back up at 15:55, I started recording at 15:57:03. After the DSP went into run, I loss the NOCC displays and remops hung. I was able to idle the DSP at 16:11:01. I hope you are able to get some data out of this pass. The DR# L01854.

Doesn't look real good. Levels were off, so only about 2% of the ADC dynamic range was used. Although there's a spike near the center of the passband that disappears about when the occultation was expected, there's a much larger signal that's about uniformly distributed between 500 and 600 Hz in the spectrum; and it's there through the whole recording. Wouldn't be surprised if the little spike is what we wanted; but I'm going to predict Dave won't want to invest much in processing this one. Good try. Thanks for the effort. Makes a quiet Sunday morning a little more exciting! ----------------------------------------------------------------------- From rsimpson Sun Mar 1 16:43:24 1998 Received: (from rsimpson@localhost) by magellan.Stanford.EDU (8.8.5/8.8.3) id QAA11632; Sun, 1 Mar 1998 16:42:52 -0800 (PST) Date: Sun, 1 Mar 1998 16:42:52 -0800 (PST) From: Dick Simpson 723-3525 Message-Id: <199803020042.QAA11632@magellan.Stanford.EDU> To: Jennifer.L.Caetta@jpl.nasa.gov, Patricia.Priest@jpl.nasa.gov, Paula.M.Eshe@jpl.nasa.gov, Salvatore.F.Abbate@jpl.nasa.gov, Sami.W.Asmar@jpl.nasa.gov, hinson@nimbus.Stanford.EDU, joe@neptune.Stanford.EDU, len@nova.Stanford.EDU, rsimpson@magellan.stanford.edu Subject: Re: Occultation #50 Content-Length: 434 Status: R Should have looked at my fancy new log file before sending the last message ... It looks as though the 100 Hz filter was used with the 5000 Hz sampling rate. The "signal" between 500 and 600 Hz is just the noise passband. The carrier is in its correct position at 1250 Hz, almost completely suppressed by the filter. It's possible that the carrier could be extracted; but I don't think this is going to be one of our better runs.
