*Specify whether FL1 or FL2 for each line in the table.
§Which peak, the first (from the left), second, ...?FL1
‡ The peak as a % of (events in gate).
Note that (events in gate) as % of (total events) is entered at the top. If you have two equal-sized peaks, the peak % of (events in gate) should be 50% and 50%, regardless of what % of the (total events) were in the scatter gate.
†Select the appropriate control, and subtract it from your sample's FI to get the CFI.
