     This is followed by the parameters for new charge spectrum (it is expected that
     this will eventually be factored out into a SPEL.2 bank).


 1   F     Polya parameter (usually called m)
 2   F     amplitude of 1st Polya
 3   F     Slope of Polya Gain 1 vs. high-half point
 4   F     Offset of Polya Gain 1 vs. high-half point
 5   F     amplitude of 2nd Polya
 6   F     Slope of Polya Gain 2 vs. high-half point
 7   F     Offset of Polya Gain 2 vs. high-half point
 8   F     Amplitude of exponential noise peak
 9   F     Falloff parameter of exponential noise peak
10   F     Max charge for normalization

     Below are parameters used for smearing of the charge spectra. There are
     two gaussian smearings, one before the discriminator and one after.

11   F     Width of noise before discriminator in ADC counts
12   F     Width of smearing before discriminator in ADC counts

     Below are parameters for simulated high-half point distribution (if the
     true high-half point is not selected---see MCMA bank).  The distribution
     of high-half points is approximated by a gaussian.

13   F      Mean of high-half point distribution
14   F      Width of high-half point distribution
 
     Below are parameters used for simulating thresholds (as opposed to using
     the thresholds recorded in the DQXX banks).

15   F      Mean of simulated threshold distribution or fixed uniform threshold
16   F      Width of simulated threshold distribution
