I figured it out.  I can just connect them to a DataSetWriter using a
script like

  pm=ProxyManager()
  energy=pm.GetProxiesOnConnection(ActiveConnection)["sources"]["IntegrateAttributes3"]
  work=pm.GetProxiesOnConnection(ActiveConnection)["sources"]["IntegrateAttributes2"]
  energy_writer=writers.DataSetWriter(Input=energy,FileType=1,FileName="energy.vtk")
  work_writer=writers.DataSetWriter(Input=work,FileType=1,FileName="work.vtk")
  energy_writer.UpdatePipeline()
  work_writer.UpdatePipeline()

That writes the data to a file.
