Butcher Results

Below are the accumulated theButcher results for Gen01. Each iteration (version) is identified and a brief summary is provided. The set of data files (see below) is available, as are any plots. Further, the FORTRAN source and the debugging output from ButcherSchool is also linked to. Where available, a link to the relevant message in the analysis mailing list archive is also provided. These refer to the Jlab archive -- the UVa version is much better but the numbering is actually different. You'll have to use the subject and date of the message to find it there.

For each iteration of theButcher, the script theButcherShop created several data files; although the content of each type of file is consistent across the versions, it was not static, so differences do exist. Also, not all types of files were always created and occasionally there are alternative versions of a file. Special cases will be addresse either in the short description below or in the message linked to. The definition of the cuts used in the respective versions can be extracted from the source, the debugging data or (sometimes) the referenced message.

The chunky files contain the event counts, total and for each cut, as determined by theButcher. They are given seperately for positive and negative beam helicity. The ground files contain the corresponding asymmetries, instead. Both asymmetry and statistical error are given, as are the corrections which are already applied. The mashed files contain total counts and rates instead of asymmetry and error. patties are successive runs averaged together (asymmetries) until either the polarization changes sign or the target cup changes between top and bottom; then a new group is started. The run number given is for the first run in the group. Lastly, the burger files contain overall averages, and also subsets of same beam and target polarization sign.

Be warned: these files (other than burger) are large and have many columns. To view them, an editor which allows horizontal scrolling and fixed fonts is needed, though viewing them in a web browser may be possible. The "burger" files are oriented vertically, so most fixed-font display options should work. They are formatted to allow access to the PID subsets by GNUPLOT.
