Peak No.§ Peak: % of (Events in Gate)‡ Disk File number Fluorescence Intensity (FI)
 FL1  1  58  3.1  025  2.5  0.6
 FL1  2  41  74  025  2.2  72

*Specify whether FL1 or FL2 for each line in the table.
§Which peak, the first (from the left), second, ...?
‡ 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.
