5.00    H.S. Wan        First version.
        N. Oblath       Moved some words from NCDP to here.
                        Add gas gain and pressure.
5.02    N. Oblath       Add straggling-simulation words, pulse scaling, 
                        and gas-gain fluctuations
5.03    N. Oblath       Added KNCMC_MIN_ION_ENERGY; Removed KNCMC_SIGMA_GAS_GAIN        
        H.S. Wan        Added 4He and 3He counters gas densities
        N. Oblath       Added pulse extension time and ncle reference parameters
	H.S. Wan        Added space charge scaling factors and low energy alpha switch.

1.  Theta is measured with respect to the anode (z axis), while phi is measured 
    with respect to the radial vector pointing *towards* the ncd anode.
