Add hlt1 filtered pAr+pp files in TestFileDB
This MR adds several simulation samples for testing purposes, with events with pAr and pp collision events. They include:
- an unfiltered sample to test hlt1 rates
- a hlt1-filtered sample to test hlt2 rates and bandwiths
- several hlt2-filtered samples to test sprucing. One sample with all IFT lines, another sample with ift FULL lines and another with ift TURBO lines. [missing: sample running on all LHCbb FULL lines]
In the samples, nu for pAr is 0.37 and for pp is 7.6 (including empty pAr events, added explicity by mixing standalone pp events according to the fraction of empty events estimated with the Poisson distribution assuming nu=0.37). They can be used to test the rate and the bandwidth, keeping in mind that nu in pAr is subject to several assumptions (see these slides for more info).
Rates obtained by the filtered hlt1 sample are reported here: hlt1_SMOG2_testlines_MB_pAr_pp_MD_fixed_SMOG2_expected_2024_mixtest_ALLIFT_checkhlt1newstack2204_evt_Full_withoutUT_TBLV.txt
The used sequence was hlt1_pp_forward_then_matching_no_ut_1000KHz, and the line Hlt1BGIPseudoPVsIRBeamBeam was prescaled manually.
