de>default = <strong>1.5</strong></code>; <code>minimum = 0.</code>)<br/>
The CD cross section for <i>p p</i> and <i>pbar p</i> collisions, 
normalized to its value at 2 TeV CM energy, expressed in mb. The energy 
dependence is then parametrized, and behaves roughly like 
<i>ln^1.5(s)</i>. Is used for the options
<code>Diffraction:PomFlux = 1 - 4</code>, while the MBR model 
(<code>= 5</code>) has its own parametrization.
