h2. Minutes from previous meeting
23
24
* Attendance: KL, PK, DR, CR, DC, AD, MU, EO, AB
25
26
* Algorithm:
27
    DC: In determining #turns, do we have enough information to tell if there could be > 1 rotation between stations? Has such a restriction been imposed — can it be imposed — in selecting “ideal events”?
28
29
* Efficiency:
30
    DC: Does MC show the same pattern of lower TKD efficiency? 
31
        — are dead channels and noise handled correctly in the MC?
32
        MU: Noise smearing added by Heidt; AD notes it’s not part of standard production
33
        KL: we don’t want to rely on the MC for this unless we really have to
34
        Action: Check dead channel & noise handling in MC
35
        Action: Check MC of this run 8681 & compare efficiencies with data
36
37
* Sources of error:
38
    CR: Need a list of sources of uncertainty: alignment, scattering, energy loss, field uniformity, etc and present what studies have been done — Action
39
40
* Unused spacepoints:
41
    DC: In adding unused spacepoint, show the distribution of distance of unused s.p & its correlation with #pe — Action
42
43
* Pt singularity:
44
    AB, DC: why not just run straight track fit 1st, if it satisfies chi2, then send to Kalman instead of trying to do a helical?
45
    Q: can Kalman reconstruct a helical from the straight?
46
    CH: Think so, if seeded properly.
47
    Action: This should be studied
