The CCDB variation "mc_sim1" is used to generate simulations for standard running conditions in 2016.

Detailed information about the files and conditions can be found at: https://halldweb.jlab.org/gluex_simulations/sim1/

Files

The simulated data can be found at JLab in /volatile/halld/sim1 with the following subdirectories:

  • rest - reconstructed events
  • smeared - hit-level data for 5% of events
  • hd_root - data quality monitoring ROOT files

Files on the volatile disk are subject to that disk's deletion policy.

All reconstructed files can be found on tape in /mss/halld/gluex_simulations/sim1/rest

How to analyze

The environment used to generate these events can be found at https://halldweb.jlab.org/jproj/projects/sim1/sim1.csh

or /group/halld/www/halldweb/html/gluex_simulations/sim1/conditions/setup_jlab.csh

That file can be used as a starting point for your own analyses. Remember that the CCDB variation "mc_sim1" should always be chosen when analyzing these files, e.g.,

setenv JANA_CALIB_CONTEXT "variation=mc_sim1"
