# Introduction - K. Long
9
# Actions from previous meeting
10 9 Rajaram, Durga
## Compare data/MC efficiencies for 8681
11 8 Rajaram, Durga
##  In adding unused spacepoint, show the distribution of distance of unused s.p & its correlation with #pe
12
##  Low pt: Consider doing a straight track fit first and pass to Kalman if it passes chi2/other requirements
13
##  Generate list of uncertainties and show what has been done so far (alignment, scattering, energy loss, field uniformity, etc)
14
## Check dead channel & noise handling in MC

h2. Minutes from previous meeting (April 27, 2017)
28 1 Rajaram, Durga
29
* Attendance: KL, PK, DR, CR, DC, AD, MU, EO, AB
30
31
* Algorithm:
32
    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”?
33
34
* Efficiency:
35
    DC: Does MC show the same pattern of lower TKD efficiency? 
36
        — are dead channels and noise handled correctly in the MC?
37
        MU: Noise smearing added by Heidt; AD notes it’s not part of standard production
38
        KL: we don’t want to rely on the MC for this unless we really have to
39
        Action: Check dead channel & noise handling in MC
40
        Action: Check MC of this run 8681 & compare efficiencies with data
41
42
* Sources of error:
43
    CR: Need a list of sources of uncertainty: alignment, scattering, energy loss, field uniformity, etc and present what studies have been done — Action
44
45
* Unused spacepoints:
46
    DC: In adding unused spacepoint, show the distribution of distance of unused s.p & its correlation with #pe — Action
47
48
* Pt singularity:
49
    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?
50
    Q: can Kalman reconstruct a helical from the straight?
51
    CH: Think so, if seeded properly.
52
    Action: This should be studied
