/* ************************************************************************

   This is the analysis query. It returns two columns for all
   signal/background events.

     - `Weight` (Positive for signal (typ. 1),
                 negative for background (typ. -0.2))
     - `LogEnergyEst` logarithm of estimated energy in GeV

   In additon, all columns provided by the 100-clause must be
   returned. (Note that you must not add a comma behind it)

   100| %100:columns
   101| %101:files:: table containing the `FileId`s to analyze.
   102| %102:runinfo:: table with the run info data
   103| %103:events:: table with the image parameters
   104| %104:positions:: table with the source positions in the camera
   105| %105:estimator:: estimator for log10 energy
