      Parameters
      ----------
      workflow: pycbc.workflow.Workflow
          The core workflow instance we are populating
      inference_files: pycbc.workflow.FileList
          The files with posterior samples.
      output_dir: str
          The directory to store result plots and files.
      parameters : list
          A ``list`` of parameters. Each parameter gets its own plot.
      name: str
          The name in the [executables] section of the configuration file
          to use.
      analysis_segs: {None, ligo.segments.Segment}
         The segment this job encompasses. If None then use the total analysis
         time from the workflow.
      tags: {None, optional}
          Tags to add to the inference executables.
  
      Returns
      -------
      pycbc.workflow.FileList
          A list of result and output files.
