<h2>Averaging over two heads : procedure</h2>
<div>
  <ul>
    <li>if both heads are open (without foil : flag = 1) - average ('FluxAve')</li>
    <li>if both heads are closed ( foil or foil + grid : flag =0[2] ) - average ('FluxAveFoil')</li>
    <li>if one of the heads is open[closed] - it is put into 'FluxAve'['FluxAveFoil']</li>
  </ul>
