R2223 mars express

        Data taken 08apr06. I did some simple processing of  file mex.002. The start of the file had the cal. The middle of file had the antenna looking at mars.

processing:

  • The planet is the echo at 20 khz.
  • The orbiter transmitter is at 31 khz.

  • I then averaged 10 minutes worth of spectra  where the planet was the strongest [utc 21.84 to 22.01]. An 8th order polynomial was fit to +/- 50Khz (excluding outliers) and then the average was divided by the fit to put the spectra in Tsys units.
