McStas Sqw component: use 'standard' Bose factor weighting #300
Should use 'standard' or 'Frommhold' Q = 2./(1+exp(-hw/kT))
This should fix issues when normalizing classical Sqw data, which result in a very large norm with the exp(hw/2kT) weighting, and most probably produces wrong results.
Related user report from Ketty Beauvois, CNRS
Dear Ken, When we met at ECNS last year in Spain, we discussed together with Björn Fåk in front of my poster "The excitations in superfluid 4He". For the data treatment, I performed multiple scattering calculations using McStas. I found a problem that I describe in the report "McStas.pdf" (attached). I tested also two other programs for the multiple scattering calculations. One is MScat (written by John Copley) and the other is written by Javier Dawidowski. I sent him a report called "multiple_scattering.pdf" (also attached), which compares the results from the three Monte Carlo programs. I would like to know if you have any idea where the problems could come from in McStas. I would be happy to discuss or respond to any questions. Best regards, Ketty Beauvois
