Fix the examples

[Juergen Reuter]

Most of the examples stumble over something.

[Juergen Reuter]

[ eeww_polarized.sin beam polarization is not working (#559); ?polarized_events flag; FATAL ERROR: Evaluating density matrix: undefined index and when commenting the histograms back in: WHIZARD BUG: histogram: name expression not implemented (yet) ... separate ticket: #604. After rewriting of the histogram expressions in r5346, this is working now. Actually, there was a missing ?rebuild_events = true . This was necessary as event files have to be rebuilt (using the same name) when changing the initial state polarization. Corrected in r5543. ]

[ dipole_subtraction.sin HUGE CONSTRUCTION AREA. But part of #51, no official example as of now.]

[ casc_desc.sin shows NaNs? in efficiency! FATAL ERROR: Simulate: reading integration grids from file 'full.vg' failed (!!!) --> separate ticket #603. This was solved now, but now it is new bug, #608. Furthermore, should be switched to pdf_builtin. After r5348, this is working. The (possible) fineprints are left to #608. ]

[ Zprime.sin should be transferred to pdf_builtin; suffers from missing s-channel mapping, also: WHIZARD BUG: Event: write raw: particle set is undefined (!!!) In r5325, added the "gw" options to the first pass, and switched to pdf_builtin. With s-channel mapping, convergence is excellent now. Still suffers from bug #602. ... This is working now, but still, 2.2 is slower as 2.1, 55s for 2.2 event generation, 16s for 2.1. ]

[ Z-lineshape.sin works in principle; but the generated analysis files are not bounded within the [88,95] GeV interval, but instead between 0 and 100 GeV and the "Data within bounds" is missing. (!). As of r5233 working. ]

[ W-endpoint.sin suffers from huge inefficiencies (cf. below, separate entry), cf. also #521. After changing the grid adaptation in the way is intended to be done by the user in r5309, this one works. (of course, the profilig issue still remains) ]

[ LEP_higgs.sin after #605 (and #603 ?) are fixed, this one is working. Updated the comments in order to explain a would-be 115 GeV Higgs in LEP searches and the much higher lumi value. ]

[ HERA_DIS.sin not yet working, syntax for beams has changed. Also, show_beams not completely/partially wrongly implemented. As of r5452, beam momenta are correctly set, but at the moment it does not work to set a PDF for only one beam (#500). As of r5535, the script runs through, the results are also the same as with 2.1, but: 2.2 is a lot slower, and the graphical analysis gives a histogram, not a plot... The missing plot options were added in r5542. It's fully working now, giving same resuls as 2.1. ]

[ EEMatching(|[1-5]|P).sin to be tested. Working as of r5662]

[ EEMatching(|[1-5]|W).sin to be tested. Working as of r5662]

[ DrellYanMatching(P/W).sin,DrellYanNoMatching.sin to be tested. Working as of r5662]

[ EENoMatchingP.sin is working. ]

The W-endpoint run in WHIZARD 2.1.1 and 2.2.0 gives huge differences in efficiency:

(could maybe be due to #57 or #375 ??, note the huge difference!)

It is the s-channel mapping when you look at the differences in the phase space:

Memo to myself (JRR): update the Wiki page once 2.2.0 is officially released.

[Juergen Reuter]

BTW, the examples are wrong on the Wiki page, e.g. the W endpoint PDF added by TO has 2,000 events in, but the SINDARIN file in the trunk and the Wiki page only has 1,000 events !!!

[Juergen Reuter]

All examples (the official ones) are working now. The Jenkins weekly examples test should be switched one again.
