6 | detector efficiencies for standard cuts | |||||||
6a | ... | |||||||
6b | ... | |||||||
7 | check of optics using ep(e', pi+) n and exclusive kaon production (peak positions and widths) | |||||||
8 | study best cuts for pi/K separation vs. momentum | |||||||
9 | study best cuts for pi/p separation | |||||||
10 | check stability in coincidence time peak (not stable in Peter's analysis) | |||||||
11 | Decide on binning in x, Q2, z, pt, phi | |||||||
12 | check stability of HMS singles rates | Anashe | ||||||
13 | Careful evaluation of random subtraction method | |||||||
14 | Check of Al subtraction for LH2, LD2 | |||||||
15 | Check stability (smoothness) of SHMS results, especially ratios | |||||||
16 | Fix as many "problem" runs as possible (usually by ending replay before end of run) | |||||||
17 | run MC for each setting: take ratio of MC/data to get corrections to SIDIS model | Anashe & Hem? | ||||||

19 | Pair-symmetric correction (plot to show is very small) | |||||||
20 | Analyze results in terms of the parameters in the proposal | |||||||
21 | How well can we separate out the cosphi and cos2phi terms? | |||||||
22 | Write PRL or PL on pion d, h results | |||||||
23 | Write PRD with also inclusion of kaon results, aluminum, and beam single-spin asymmetries |
