ESA Data

You can have easy access to all data files via de weblink to all the data present on disk. If you don't have any easy storage capacity to analyse the root files present, you can easily get them loaded in root via the TWebFile class, where you open a rootfile as:

TWebFile f( "http://www.hep.ucl.ac.uk/lc/T474/EsaData/root.0/run-2740.root" );

• Data Quality plots : raw repository with all the DQ plots generated from the dataquality scripts in esa/offline-yury/dataquality (cvs)
• Data repository at UCL with all the gzipped raw datafiles, the online processed, Yury style root files, the reprocessed root files and the new libbpm style root files.
• Run information database, the links to the individual runlists for each period have been replaced by the run information database. You can now retrieve specialised runlists selecting only certain types of runs...
• July 2007 run :
  Zygo fast data runlist
  TDS scope waveform data
• DOCUMENTATION ABOUT YURY'S CODE : how to run your own copy and how to process the raw files, how the code is setup and what is in the ntuples...
• Raw and reprocessed data that was taken with the TDS Oscilloscope vi.
