Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.
Inline: Display the subject line only or also the text of the posting(s); for the choice "All" the "Outline" choices are switched off.
|1||0||1||no text / full text of posting|
|2||1||All||text for level 1 only / text for All postings|
Outline: Choose the depth of the posting thread, successive toggle controls provide increasing detail.
|1||2||1||2 levels / 1 level (original posting)|
|2||3||2||3 levels / 2 levels|
|3||3||All||3 levels / all levels (all postings)|
Thank you for your response. As can be seen from the attached graphs, substituting
hadrPhysicsList.push_back( new HadronPhysicsFTFP_BERT()) (fig 1) or hadrPhysicsList.push_back( new HadronPhysicsQGSP_FTFP_BERT()) (fig 2)
hadrPhysicsList.push_back( new HadronPhysicsQGSP_BIC_HP())
made a small theta drop-off to start at smaller angles, and not as abruptly (although QGSP_FTFP_BERT smoothed the whole picture way too much), whereas, putting
hadrPhysicsList.push_back( new G4HadronInelasticQBBC()) (fig 3)
in its place, did not really change anything.
But in each case, the small angle drop-off is still present.
