New Client Reply: Problem with SPLIT

>It appears that your target source has 3 different

The target NGC6240 has 2 different source numbers in my data set.
SPLIT recognizes  only #4, but  does not #1 after running SPLIT.
                                                                                  No. vis

The sources numbers are #1 and #4.

I renumbered #1 to #4 by running  DSORC. (aparm(1)=1, bparm(1)=4)

I did TABP with PIXXY=2,1,1 (the row# =1), the #raw is obtained by PRTAB.

>Do something similar to the other obsolete source table row.
I don't do this for other sources as I need to correct only the target. Correct?

I did run LISTR to make sure that all target visibilities went to #4. 
Seems okay. # visibilities of #4 is 245375 = 243425(#1)+1950 (fmr. #4)
and #1 is 0.
 But, #2 (3c286) has no  visibilities and its source ID changed to be 0 from 2.
Don't know why. I decided not to care about 3c286 as I need only target ones.
                                                                                         No. vis

Then, I ran SPLIT (sources = NGC6240) but did not get all target visibilities.
#Visibilities are reduced to from 245375 => 152560.
Do you have any idea? Where are lost  visibilities gone on my disk?

How can I make this? DO I need this operation in this case?

Thank you.
