[daip] SPLIT problem

[Takayuki HAYASHI]

Dear DAIP,

Now, I'm analysing the VLBA data in which RHCP of MK have some problems.
So, there are following data.

     LL and LR which includes MK
     LL, RR, RL, LR (FULL stokes) which doesn't includes MK

I tried to SPLIT the data and FITTP to make UVFITS
so that make image by Difmap.
However, it seems that SPLIT uses the data which both RR and LL are 
included and all the data of MK are removed.
(Until I SPLIT the data there are stokes LR and LL of MK baseline 
without fail.)

Could you tell me how to include stokes LL and RL data of MK ?
