[Rivet] ATLAS-CONF-2011-038 data histogramsJames Monk jmonk at hep.ucl.ac.ukTue Sep 13 16:04:05 BST 2011
Hi Steffen, My strategy was always to keep the separate histograms of the vetoed and inclusive distributions, which are simple event counts that can be added across many files. However, I see that in the Rivet trunk version it deliberately deletes the separate event counts and only stores the final result, e.g. by destroying the histogram here: http://projects.hepforge.org/rivet/trac/browser/trunk/src/Analyses/ATLAS_2011_S9126244.cc#L339 So maybe the best thing to do would be not to delete the event count histos (even though they are not part of the published result). Maybe someone on the Rivet mailing list has a better idea - the problem of merging many subjobs is quite common I think. In this case the analysis requires an extremely large number of events, which can only really be accomplished by many sub jobs. cheers, James On 13 Sep 2011, at 15:44, Steffen Schumann wrote: > > Hi Andy, > > I am currently looking into your analysis with Rivet.

This doesn't give me good statistics in the high pT or dY bins however. I am forced to combine serval (hundreds) of rivet aida output files to get decent statistics. My problem is that a simple add and divide script doesn't do the job as the is no realy bookkeeping of event numbers or bin entries in Rivet. Accordingly I can't really trust what I get from the combined runs for bins that are only sparsely filled. > > Do you happen do have an advanced script that can do such a combination of several runs in the correct manner or alternatively do you know a strategy how to do it correctly? > > Thanks for your kind help. > > Cheers, > Steffen > > > > Quoting Andrew Pilkington <andrew.pilkington at cern.ch>: > >> Dear Steffen, >> >> The code is in the trunk version of Rivet at: http://projects.hepforge.org/rivet/trac/changeset/3319 >> >> I have cc'd James Monk into this chain.

I wanted to have a look at the Rivet implementation of your analysis. However, neither in the Rivet online documentation of standard & new analyses nor in the Rivet-1.6.0 source code I could find the corresponding routines. Could you point me to the analysis code please and maybe give me some instructions in case I need to manipulate Rivet? >>> >>> Cheers, >>> Steffen >>> >>> >>> Quoting Andrew Pilkington <andrew.pilkington at cern.ch>: >>> >>>> Dear Steffen, >>>> >>>> I'm re-contacting you regarding the jet veto data that you expressed an interest in a couple of months ago. >>>> >>>> I'm extremely happy to say that our paper is now available and submitted to arXiv/JHEP. The ATLAS public version is here: https://atlas.web.cern.ch/Atlas/GROUPS/PHYSICS/PAPERS/STDM-2011-03/ . The data tables, which will be sent to HEPDATA this weekend, have been validated and are attached to this mail. Feel free to ask any questions if you would like some more information. >>>> >>>> A Rivet routine is being validated and should be available next week. >>>> >>>> Cheers >>>> >>>> Andy and Mario >>>> >>>> >>>> >>>> On 29 Mar 2011, at 13:50, Steffen Schumann wrote: >>>> >>>>> >>>>> Hi Mario, >>>>> >>>>> thanks for your reply. It's a pity that you are not allowed to share the data shown in conf notes -- in particular as sometimes the time until measurements finally get published can be quite long.
