<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 < 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>
