<h1>EPIC ICS: low resolution spectra: averaged over two heads</h1>
<h2>Averaging over two heads: procedure</h2>
<div>
  <ul>
    <li>if both heads are open (without foil : flag = 1) - average</li>
    <li>if both heads are closed ( foil or foil + grid : flag = 0[2] ) - average</li>
    <li>if one of the heads is open (flag = 1) - its value is taken</li>
    <li>if only one of the heads has flag &lt; 3 and is closed (flag = 0/2) - its value is taken</li>
  </ul>
  <p>While energy spectra plotting <i>flag</i> value is taken into account for correct Energy Table</p>
  <p>Derived parameter - flag is not taken into account - so each energy channel is a mixture of open/closed
    moments.</p>
