Fast simulations
Downloading ROOT files
Files after fast detector simulations are created using Delphes program. Assuming that you have installed either hs-tools or Jas4pp programs, you can use “hs-*” commands. You can find all samples that have “rfast” tag for download. Click here: http://atlaswww.hep.anl.gov/hepsim/list.php?find=rfast. If you need to find all ROOT files for a give tag, say rfast004, use this command:
hs-find tev14_mg5%rfast004
which searches for all samples with the dataset name “tev14_mg5” (Madgraph5, 14 TeV samples). Then download a selected sample as:
hs-get tev14_mg5_nlo_httbar%rfast004
The description of the detector tags is given in Detector description.
