What was the difficulty?

• introducing the hadronic calibration in MC is
  complex
• no one had a clear picture of all the components
  being used
• for p17.09 we did not have consistent sets of
  files to test (d0gstar output, 0-bias overlay
  files) until mid February despite hints that
  something is not working correctly and several
  requests being made
• ?difficult to debug beyond having code that
  compiles and looks reasonable
• ?difficult to catch the logical flaws

What about the calorimeter code?

• Short term
• p17.09.04 will allow to fix p17.09 MC p17.06
  0bias overlay
• ?timescale build on Wednesday
• ?same JES as p17.06 MC with p17.08 fixer
• p17.10 will give a correct overlay with p17.09
  0-bias
• ?timescale build on Friday or next Monday
• ?slight differences for JES could be expected
• ?MC/data comparisons to tune ADC guess?
• p20 is cleaned up and will contain the
  functionalities of p17.10
• ?we do not plan to implement any further
  functionalities
• ?we do not need any speed up
• ?what we have now has been (painfully) debugged
• Personally I dont plan to make any further
  developments, and my main goal is to finish the
  documentation

10
Should we rewrite?

• If it aint broken
• the code could certainly be streamlined
• it is certainly not a good example of C
  programming nor OO design
• it has grown over the last year to become fairly
  complex
• handles data calibration from DB
• handles fixing options
• handles L3 from files
• handles 0-bias overlay, simulation and
  MC-reconstruction
• it will be a real effort to rewrite with some
  risk involved
• what would be the real gain for the data quality?
• but, I would be off the hook!!!!
