The idea here is to list open questions, outline the proposed method for answering the questions, and prioritize the tasks.

Questions Generated from recent teleconference

Addressed during week of 10/15/2008

  • Double check the (y,z) distribution with nContEH ; also look at the y distribution where each z slice is normalized, to see if things are truly downward biased
    • Interesting results to both questions in this elog

Remain Open

  • Dave suggets start time scan for midplane gondolas, without nContEH cut. If OEH mustops leak into 1EH mustops, this should disappear at some point and become stable.
  • Peter Winter suggests a similar stop time scan for downward going ones
  • I suggest adding up all upward going guys (1-3, 16->14) and looking for gondola variations
  • I need to redo the shrubs where the z_electron is the z_tracked back to the tpc frame
  • For sara: Given a small abs(theta), look to see if the nCont distribution is different for different y-slices

  • Use the event display to examine nExEL >= 16. Are these scatters, sparks, something else?
  • Repeat the nExEL scan with a cut on the fit to the extra EL pointing/not pointing to the stop
    • This involves setting up some simple 2nd-level tracking to fit the extra pixels
    • Check auxptr and TTwoLine info in the mustop tree (for visualization on event display and observe available chi-square information)
  • Check hypothesis that the decay modifies the nContEH part of the track by making requirements that the Michel is upward going
  • Dave suggests that making plots versus theta (or gondola z), rather than just phi
  • Compare the muplus fits to the muminus
    • i peter refines the 7-parameter fit
    • make use of the par-scan macros
  • make simple, spatial plots (x,y,z vs, nExEL, nContEH)
    • run shrub level
    • add to the main mta analysis
  • Define the nExEL variable for nIslands > 1 (currently no extra EL pixel information is collected)
    • NExEL for island i = (nExEL - sum EL in all real islands)
    • Consider using IsNotAlone for cuts
  • Peter W. asks for cvs update with new shrub additions (best entrance flag, HasBestEntranceIgnoringSparks(), etc)
  • Simple 1 parameter model to show how distortion for a given gondola for n nContEH depends on the relative statistics in bin n and n-1
  • gond:dt:nContEH | angle of decay electron (upstream vs downstream)
  • gond:dt:nContEH | angle of decay elec | y_stop height

Addressed during week of 10/8/2008

  • make simple, spatial plots (x,y,z vs, nExEL, nContEH)
    • y vs nContEH : see this elog and this elog
  • Check hypothesis that the decay modifies the nContEH part of the track by making requirements that the Michel is upward going
    • lambda vs gondola | nContEH : see this elog and this elog

  • Use the event display to examine nContEH >= 8. Are these real or do they have funny topologies?
    • event display for nContEH >= 8: here
  • Resolve the difference between lambda vs nExEL | nContEH = 1 and lambda vs nCont = 1 | nExEL <=18
  • Determine how the head cut is stored
    • Answer: IsTrack() and other oneline fits, etc only stored when el_max - eh_max is small enough

Outstanding Tasks / Questions

  • Need to perform a monte carlo to understand the banks bump equivalent for the LESS mode
