KOKEE/KOKEE12M ties experiment.

  The primary goal of the experiment is to estimate the position of 
KOKEE with respect to KOKEE12M using phase delays. The secondary
goal is to investigate instrumental errors by examining the 
differences between phase and group delays. Scan are 40 second
long in this expriment.

  The experiment is performed at X-band at 10 IFs of 16MHz wide 
spread over a range of [8.4164, 8.8964] GHz. KOKEE records 16 IFs 
in the right circular polarization, but only 10 are used for 
correlation. KOKEE12M records 8 IFs in dual band. Correlation is 
performed using the zoom DiFX feature. There are 91 AGNs with the 
total flux density at 8 GHz > 1.5 Jy in the source list.

  This experiment should be correlated with a resolution of 10 KHz
in order to sample phase calibration tones exactly. The following
parameters defined in kt013.v2d should be used in correlation:
