echidna meeting 2014-12-19

Introduction

Introduced the idea of Echidna as a user-friendly, fast-running limit setting and background fitting software - to set limits on neutrinoless double beta decay, exotic models and solar neutrino signals. It also provides a useful cross check of Andy's limit setting code.

Phil's pull request

• Chosen a generic python directory structure
  • main directory contains directory with same name as the software plus docs directory
    • sphinx documentation
  • echidna directory contains core (bulk of code) and test (unittests) directories
• Core data structure:
  • numpy array
  • Method to return profile
  • Method for sum of data structure
    • Ed: people will want to see root histograms
      • Phil with add method to return TH1D for example
    • James: how are we going to save data files
      • General consensus that pickl files would be best

Next steps

• Smearing should happen after we have loaded root file from rat
  • smearing binned data
• Added new members: Ed
• Added and assigned GitHub issues

Snopy

• Phil gave a quick overview of snopy
• Key difference is use of analytic spectra - not what we want to do for echidna
• We can take aspects of snopy into echidna though

User scripts

Scripts run by the user should be simple, just a few lines of commands
