How does/should SasView handle zero intensities?

Zero intensities can arise in a reduced data file as a result of
'beam blocked' or 'electronic background' measurements, or masking.

Issues arising are:

  • how does one discern between genuinely zero intensities and

intensities that (for whatever reason) are unknown or to be ignored;

  • what uncertainty should be assigned to a zero intensity? (The issue

of zero uncertainties has been previously raised as a problem);

  • should SasView? have a 'how to handle zeros' option in its View →

Startup Setting, for example (AJJ suggestion)?
