-\\ +PS. Some time during the changing of RF cablesthe frequency of the front end oscillator was changed inadvertently. The knob must have been bumped one notch such that our sky recording frequency went up by 20 KHz precisely. This was discovered when preparing for the next experiment and coherence could not be found for the same set up. If it is possible to correlate with one station having a 20 KHz offset then that would be excellent!
