This was done over DSS-14 today (DOY 262, BOT 3:40 p.m. PDT). I ran two RSRs: one using DSN generated predicts, and the other using Radio Science generated predicts. I recorded on four channels per RSR using the following bandwidths: 1k, 2k, 4k, and 8k Hz. This adds up to 8 RSR data files. The RSR and DSP data times are 01-262/23:35:00 to 01-263/00:40:00. I transferred the RSR data to /users/m9/data/aseel on magellan. The files names are 01.262.14.2335-0040.XY.rsr where: X = 1, 2, 4 or 8 for 1k, 2k, 4k and 8k Hz bandwidths, respectively. Y = d or r for DSN and Radio Science predicts, respectively. The DSP data are on the CDR and ready to be queried.

I knew that we needed 16-bit samples. That's what I've used before. I remember setting the configuration to 16-bits, but I also remember that I had a problem loading the predicts so I disconnected and reconnected to the RSR. The default configuration is 8-bit, so I fear that I may have forgotten to reset it to 16-bits. I'm terribly sorry. I will reschedule a pass to collect the data again. I hope that you didn't already spend much time looking at the data. -Aseel > Aseel: > > All of the data collected on day 262 appear to have been > collected with 8-bit samples.
