Hi,
> You neglect to tell me what data you are using

Sorry about that.
My project, BY012 (scheduled for:_2000_05_12 13:00:00 GMT, using the
VLBA and a VLA antenna) was correlated on the VLBA Correlator in
Socorro, New Mexico.

--------------- Correlation Parameter Summary---------
           Number of stations =  11
          Spectral resolution = 256 spectral points
             Integration time =  4.000 seconds
           Cross Polarization = No
             Window Weighting = UNIFORM
           Source coordinates = from Standard Correlator Catalog
            Distribution tape = DAT

So if I understand correct, fitld shouldn't call for this BA2BP
on my data. I wonder then why it happened ---am I making a stupid
question here?  :(
