I'd like to make a request for D_s+ embedding in the Run7 Au+Au
P08ic dataset. Here are the specifications,

1) P08ic Geometry
2) SVT events only
3) 100k events of D_s+ -> phi pi+ -> K+ K- pi+ (at 100% B.R. for each step)
4) 100k events of D_s- -> phi pi- -> K+ K- pi- (at 100% B.R. for each step)
5) D_s 5% of multiplicity
6) pt flat 0 <= pt < 4 GeV/c
7) y flat, |y| < 1.0
8) |vertex Z| < 20.0 cm

5% mult per event

* Use production P07ic and library SL08f. Requested trigger id is 66007. Update correct single particle MC information. Note: this is 'LambdaBar1520' request but use 'Lambda1520' in single particle MC because there is no 'LambdaBar1520' in the particle list (Hiroshi)

Upsilon embedding in 2007 AuAu

Generator: Upsilon flat in pt
Number of events: 30k for each Upsilon state (1S, 2S, 3S)
Trigger : 200602

Description/Instructions:
Generate 3 separate datasets corresponding to each of the Upsilon
states (1S, 2S, and 3S) each of 30k events.
Generate exactly 1 Upsilon per event with the following phase space:

1. Flat in pT from 0 to 5 GeV/c
2. Flat in y from -1.5 to 1.5
3. Upsilon -> e+ e- decay channel only, in GSTAR

Mix the Upsilon into a real Au+Au st_upsilon event at sqrt(s)=200 GeV.

GSTAR run:

Geometry: Most current year 2007 geometry
Hadronic interactions: on
Field: 0.5 T

Embedding:

Embed Upsilon into 2007 Au+Au minimum bias real event.

Reconstruction:

TPC simulator: trs

No vertex Z selection
