Effects not considered here


б 

The following effects which can also contribute to the "noise" are not taken into consideration here:


б 

  • Errors in the calibration of the complex gains,
  • atmospheric amplitude and phase instabilities,
  • sidelobe effects,
  • source confusion,
  • radio frequency interference,
  • bandwidth distortions,
  • correlator DC offsets.

The term noise is put in parentheses, because these effects are in part systematic, not random, and thus influence the data quality in a different way than real noise. They must also be treated differently in the process of data reduction, if detected.
