Mev file contains both integrated and median intensities. Selecting Median or Integrated will place either of them immediately after UID. By default, the background is subtracted and they are calculated with following formulas:
Integrated Intensity = F Pix × (Fxxx Median - Bxxx Median) × ( 1 - Fxxx % Sat)
Median Intensity = Fxxx Median - Bxxx Median
UID = consequential number during processing
