Documenting CTF work

• As the CTF task rapidly approaches completion, we
  need to start focusing on documenting our work.
  Given the broad reach of our involvements, it
  will not be an easy task, and it seems best to
  break it up into smaller sections, each under the
  oversight of a designated person.
• At the moment we are considering the following
  sections
• Overview of the calorimeter electronics and noise
  characteristics.
• Overview of the impact of noise on calorimeter
  data (mostly jets and MET) at 1.5sigma zesu, soft
  2.5, full 2.5
• Cell level studies of pedestals/noise, SCA
  issues, non-linearity
• EM issues resolutions, fakes, comparisons of MC
  to data.

• JES issues resolutions, response, jet shapes in
  MC and data.
• Jet and MET issues fake jets, MET resolutions,
  analysis cuts for p11 and p13 (brief reference to
  other sources), new algorithmic solutions.
• Tau issues, discrimination between taus and QCD.
• Muon issues, detecting isolated muons in the
  calorimeter.
• Noise simulation new pileup (including new
  format for input data), verification through cell
  level MC to data comparisons.
• Code issues caldata, offline suppression,
  verification of layer weights
• L3 status of zero-suppression, MET, jet
  algorithms.
• CTF MC production list of files and conditions
  for zesu, data set definitions
• "Toy" MC studies
• Conclusions and recommendations
• List of suggested follow-up studies/code
  developments, with a brief discussion

Documenting CTF work

• We foresee the following stages (for each of the
  sections)
• 1. A half to one page summary of the major
  results and conclusions, and a (small) set of
  plots supporting the conclusions. This is needed
  to be accomplished on the time scale of the
  coming CTF workshop (Feb 10), and our report to
  the collaboration (Feb 14). We expect that it
  would also lead to a more expanded presentation
  and discussion at the workshop.
  For the workshop and the
  recommendations we have to focus on achieving
  clear conclusions about the impact of zero
  suppression on each major aspect of our studies,
  rather than just go through a collection of
  reports on latest plots.

• 2. A longer (2-3 page) description that includes
  some technical details, pointers to other
  sources of information, and a somewhat more
  expanded set of plots. It should be compact but
  self-contained, and able to serve as a reference
  for the longer term. This should become our
  main document (presumably a DØ note). The time
  scale for this step is not as rigid as the
  previous, but we should try to have a complete
  set of sections by the end of February, to be
  followed by a rapid editorial process for the
  complete document.
