The depositions server asks for total reflections. I assume it wants only those unique reflections we were able to
collect, regardless of the sigma cut off. These are called 'observed'. The total we use in refinement will be a subset

From Phil Jeffrey, a small correction to my previous answer: usually it is acceptable to filter out observations with I/sigma < -3. (This is done internally by the data processing software and/or truncate or the Phenix equivalent.)
