-When a sound signal occurred, Miller estimated the fringe shift and called it out.+When a signal occurred, Miller estimated the interferometric fringe shift and called it out.
 An assistant recorded that number on the spreadsheet. An assistant recorded that number on the spreadsheet.
  
 As the interferometer turned through one revolution, the numbers were entered in one row. As the interferometer turned through one revolution, the numbers were entered in one row.
