Selection/Reco criteria:

1. Running on "GOODCOLL skim" files /store/dataCommissioning10/MinimumBias/RAW-RECO/...; runs 132960 lumi sections 1-MAX. and 132961 lumi sections 1-227. (NB: Some of the plot titles below indicate both runs, others indicate only one. All of the plots though have both run's data in them except the run info plots.)
2. Require L1 trigger bit mask: "0 AND (40 OR 41) AND NOT (36 OR 37 OR 38 OR 39)")
3. "OneGoodVertexFilter" and beam scraping filter also applied (note that the GOODCOLL skim only applies this and the previous requirements in an "OR" configuration).
4. Require BX=1
5. Reco window considers time samples 2-5
6. Reject rechits with quality flags 0,1,18, or 19 set (see Jeff's twiki)
7. Only hits above 5 GeV considered
8. Only hits with peak sample in TS3 or TS4 considered
9. Igor's PET algorithm for determining PMT hits from two paired hits (L,S) from a given tower causes a different histogram to be filled. (The algorithm is implemented as defined in a talk given by Dinko a few weeks ago.)
10. Non-PMT hits with matching hit in the other depth (and both above threshold) are considered "verified", otherwise they are "unconfirmed"
11. The metric TS4/TS3+TS4 is formed from the digi in fC (no ped subtraction, no gains applied) for verified, unconfirmed, and PMT hits.
