Typically you get this message when the timerange specified does not contain
any PC calibration information - I haven't looked at your uvdata, only at the
calibration file from the auxiliary data (ie bl149becal.vlba.gz) and it
appears that the auxilliary data only contains info from UT timerange:
2006AUG12/224 at 03:20:00 to 2006AUG12/224 at 04:20:59. I'm not sure what
happened and what other problems this may cause for your data but it may
explain the error message you get in all versions when you use the auxiliary
data. Looking at the TSM plots I see that PC data should have been included
in the correlated data for the full 24 hours, but as typically PC data is
taken once a couple of minutes maybe you should check that all antennas have
PC data in the small timerange you specify, eg by plotting the PC table for
that range. Hope this helps
