... Both selfcal and gpscal assume that the gains are independent of frequency. ... If all the visibilities for a given baseline go through one signal path, then the instrumental phase for the different visibilities should be equal (assuming the signal path is well equalised). ... If the visibilities for a given baseline go through multiple signal paths ( e.g. the 2 IF system for the ATCA), then the instrumental phases for the different paths could be significantly different. ...

... Thomson's multiple window method of spectral estimationthomson provides a very good estimate of the power spectrum by measuring the energy contained within a collection of rectangular shaped frequency intervals. ... Often, much of the fine structure of a spectral estimate is due to noise. It should be stressed that while other methods of spectral estimation (such as the Welchoppenheim method) exist, the Thomson method is particularly noteworthy for its precisely defined rectangular frequency bins. ...
