Getting started with the new bookkeeping

Introduction

The bookkeeping gives you the filenames of all data-files.

The quickest way to look at the bookkeeping is via the Dirac-Webinterface (Data > Bookkeeping). You find data usually under a path like: LHCb/Collision11/Beam3500GeV-VeloClosed-MagDown/Real Data/Reco12/Stripping17/90000000 ( Full stream )

Finding Monte Carlo Files

If you are looking for Monte Carlo files, make sure to change the query order to “Event type”-first. Otherwise you will need to search through many folders to find the files you are looking for. To get more information on the Event Types see eventtypes.

Starting the bookkeeping locally in Zurich

Just log into one of the grid-machines. You can then start the bookkeeping browser as on lxplus.
