Introduction

• Im using ROOT to develop an Analysis Framework
  for the data coming from 84 channel/cell tower
• Want to create a software with a user interface
  that
• Analyzse data from each of the 84 channels the
  same way so that they can be compared
• Sets parameters with buttons and other controls
• Removes pedestal and crosstalk
• Fits multiple gaussians, poissons and landau
  curves to histogram (all 84 channels)
• Enters data conditionally into histograms (for
  example only add event data from Channel X if
  events from Channels Y and Z are in MIP range)
• Displays channel data by layer or column
• Displays Scatter plots

Current Status

• Using ROOT because I was able to get up and
  running quickly
• I now have simple software that
• Reads one of my flat data files
• Displays the histograms of a layer of 7 cells
• Allows me to click on one histogram to expand it
  to make it easier to see

Problems

• Still have difficulty with system not compiling
  and linking correctly
• Still cant create user interface because of
  these linking problems

Next Steps

• Immediate next steps
• experiment with fitting examples
• switch between layers
• at very least get mean and sigma for any channel
  we want
• Longer term next steps
• learn how to compile instead of just interpret
  code
• include user interface widgets
• write code to remove pedestal
• write code to removed crosstalk
