     It does this only if SOLINT is less than zero - and that is
ecause sources get mixed together in that case.

I tried to build a data set to look like this using TBIN and TBOUT and
could not repeat this problem.  The QUAL adverb does enter in source
selection from the source table, but source number 0 in the BP table
then ignores any source selection and the error return from the source
selection is also ignored.  I got correct plots for the requested
FREQID indepndent of the QUAL value.
