[daip] SOUFIL: ALL SOURCES REJECTED BY SELECTION CRITERIA error

Dear Eric
Following is the result of running PRTAB with INEXT = SU on
a multi-format UV-data file containing a single source.
[In case the text appears jumbled on the mail-page, I have
also attached a text file that should be easy to view.]
UVPLT fails for all apparently valid combinations of the following
relevant parameters after it had been set to:
task 'UVPLT'
default UVPLT
getn 1 (relevant multi format file)
dotv 1
Now the following parameters are fiddled around with, and the result of
the UVPLT run is indicated in the success/failure column:
------------------------------------------------------------------------------------------------------------
PAR Values tried sequentially
Success/Failure
------------------------------------------------------------------------------------------------------------
1) QUAL
-1/1 Failed
2) CALCODE '
' Failed
3) FREQID
-1/1 Failed
4) Sources '3C345'
' Failed
Sources '
' Succeeded
------------------------------------------------------------------------------------------------------------
It is true that the source's Flux density in the SU table are all 0. But the
data being gain-calibrated at earlier stages of the processing, the flux
density scales in the "successful" UVPLT run (ie., with sources = ' ' )
comes out correct. Only when the source-name is specified, there appears
the problem -- " SOUFIL: ALL SOURCES REJECTED BY SELECTION CRITERIA"
Can some trailing SPACE-charatcers in the source-name cause this problem?
regards
