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 10/8/2008

• 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

## Remain Open

• 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
