[daip] UVFIX with two subarrays question

[Leonia Kogan]

My previous concern about twice recalculation B1950=>J2000 may be 
correct for multiple source data only.
So it can not be applied to your single source data.

So the both parts of dbcon'ed data observed the same (one) source but 
different UV.  Do they?
And the coordinates of the source at the headers are different because 
the different epoch. Are they?
