  1. Define classes for tracking infrastructure
  2. Define a cheater for SimTrackHit to whatever it is that is used as input for pattern recognition.
    • Rob will do this once the endpoint is defined.
  3. Re: links back and forth between Geometry and TrackerHits
    • Do we need full bidirectionality, as Jeremy has suggested, or is one way enough.
  4. Re: Forward geometry.
    • Can Hans present a road map?
  5. How does the above affect tracking algorithms?
    • This was written in response to Rob's comments that we need to resolve:
      • Cylindrical vs polyhedral issue.
      • Version control.

The heading refers to data flow pictures. Dima's is on page 4 of his slides (attached) and Rob's is on page 8 of his slides: http://docdb.fnal.gov/ILC-public/DocDB/ShowDocument?docid=402Image Removed

  • There are a lot of similarities in these pictures.
    • Dima's DigiTrackerHit box is conceptually similar to Rob's box 17
    • Dima's TrackerCluster class is conceptually similar to Rob's box 7.
  • Dima's picture does not have the analog of box 5 in Rob's picture.
    • This represents a box that can be populated either by MC or by real data.
    • When populated by MC, it is intended to look exactly like real data.
