Simply, no.  Did you invoke any of the special options of OOSUB - it
will do frequency dependent visibility subtractions/divisions?
Otherwise it should be the same as UVSUB.  From this I cannot even
tell whether say the SN table has troubles or the UV data.  Signal 11
is an addressing exception ("segmentation") but for what I cannot
tell.  If you could make the UV data file available I might be able to
tell but the FITS writer/reader might mask the problem anyway.
