BTeV Analysis Software Considerations for the
Average User

2
Fundamentals I(Unix Level Commands)

• C and Bash shell compatible
• Setup by copying and executing one file
• Sample files for the most common analysis cases
• Simple pickup of .c and .F files
• Ability to checkout (and use) groups of constants
  to be modified
• Simple Control File with analysis commands

3
Fundamentals IIInteractive Analysis

• Interactive analysis commands same as in Control
  File
• Interactively interruptable analysis
• User read of new constants during analysis
• Reanalyze command
• Physics parameters easily available (dumps)
• Output partial statistics and histograms/ntuples
• Single Event Display

4
Fundamentals IIISingle Event Display-level 1

• Selectable xyz and angle ranges and scales
• Color code track types
• Selectable track types (, -, flavor, max chisq,
  fit type, etc)
• Clickable tracks to show more info (momentum,
  flavor, vtx, etc)
• Clickable vertices to highlight its tracks
• Clickable detectors to show additional
  information such as pulse heights, hit positions,
  etc

5
Fundamentals IIISingle Event Display-level 2

• Remove a hit from a track and recalculate a
  momentum, vertex...
• Remove tracks from vertices and refit
• Attach a (different) flavor to a track and
  calculate a mass hypothesis (kink or vee)
• Read in new constants and refit
• Etc.

6
Fundamentals IVAnalysis Termination

• Ability to quit interactive analysis with no
  output
• Exit interactive analysis with full output
• Interrupt batch analysis (quit or exit normally
  at current event)
• Standard exit on CPU, clock time or Event limits.
• Readable exit codes (web help?)
• Etc.
