[neutron-mc] Monochromator_flat

[Ulrich C. Wildgruber MPI fuer Metallforschung Stuttgart]

Dear colleagues,

just today I looked at the source code of "Monochromator_flat.comp" and got
stuck at:

  double Gauss_X[] = {-0.987992518020485, 0.937273392400706, 0.848206583410427,
                 0.724417731360170, 0.570972172608539, 0.394151347077563,
                 0.201194093997435, 0, 0.201194093997435,
                 0.394151347077563, 0.570972172608539, 0.724417731360170,
                 0.848206583410427, 0.937273392400706, 0.987992518020485};

Could it be that the lonely minus-sign attached to the first element
is wrong or that other minus signs are missing? I wasn't able to get
hold of the literature mentioned in the source listing.
(/* Values for Gauss quadrature. Taken from Brice Carnahan, H. A. Luther and
      James O Wilkes, "Applied numerical methods", Wiley, 1996, page 103. */)

Can anybody please confirm that everything is all right?

Thanks!

Uli
