I've written a simple script which gets the luminosity for the runs in a given file. The working directory is /cdf/data32a/cwolfe/lumi The script is getlumi.tcsh You run it like so: getlumi.tcsh goodrunlist file_name So, the first option is your goodrun list. If you just want to use all of the runs, there's an allrun.list file in the directory which has all of the runs in the offline database (up to the date of the file). The second option tells the script which file(s) to run over. If you want to give it multiple files or wildcards, use quotes. e.g. here's the command to run over the 4.11.1 tight muon remake samples: cdf32:/cdf/data32a/cwolfe/lumi>getlumi.tcsh ./goodrun.list /cdf/data10a/Datasets/non_express/muon/UCntuples/4.8.4a_remake4.11.1_tight/"*.root" And here's the result: Offline: 115884.726715 , Online: 114171.759288 Best value offline: 115884.726715 online: 0 sum: 115884.726715 If you have any questions, let me know. -- Collin (cwolfe@hep.uchicago.edu)
