Goal: to reveal a fine feature in the complex bandpass in order
      to improve phase calibration. The feasibility of 
      "freezing" of a non-linear feature for processing consecutive
      observations will be investigated. If non-linear features
      are indeed stable, then this can be used as an a priori for 
      polarization bandpass calibration. In that case only
      a phase offset and a phase rate per IF can be adjusted.
      The reduction of degrees of freedom will improve robustness
      of polarization bandpass determination.

Success criteria: to determine non-linearity in phase and amplitude
                  bandpass with a high fidelity.

Two sources will be observed: NRAO150 and 0552+398 for 5  minutes.
The second source was reported to have linear polarization
Thus, consistency of polarization bandpass calibration for polarized
and unpolarized sources will be evaluated.
Both sources have correlated flux density over 1 Jy at baselines 
longer than 5000 km.
