Analysis of R1675 experiment:

• Autocorrelation looks normal

  Autocorrelation at X-band:

  Autocorrelation at S-band:

  

  I masked out autocorrelation at 2.36674 MHz (red circle)w

• Bandpass look normal:

  Fringe plot before applying the bandpass calibration:

  

  Fringe plot after applying bandpass calibration:

  

• Short term phase stability is good:

  Fringe amplitude and fringe phase as a function of time:

  

• Phase calibration is not implemented yet.

• System temperature is in a in a range of 45-60K with slight elevation dependence at elevations below 20°r;

  

  

  The system temperature about 10% greater at S-band:

  

• Post-fit residuals are in a range 30–40 ps, which is normal:

  

• Plot of residual atmosphere path delay in zenith direction does not show abnormalities that would indicate elevation-dependent systematic errors:

  

• Finally, results of determination of RAEGYEB positions using all VLBI data since 1980.04.11 through 2015, including experiment r1675 on 2015.02.16 with station RAEGYEB. Velocity of RAEGYEB is tied to velocity of YEBES40M.
