Query: Reproducing pairs of measurable functions and partial inner product
  spaces   We continue the analysis of reproducing pairs of weakly measurable functions,
which generalize continuous frames. More precisely, we examine the case where
the defining measurable functions take their values in a partial inner product
space (PIP spaces). Several examples, both discrete and continuous, are
presented.
