* 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)

From Sarah Lapointe:

I would like to make a request for D0 and D0bar embedding in minbias Au+Au
200GeV run7 production p08ic.

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 

This embedding will be used to look at high pT electrons like those found in W events and test all detector responses are in order (TPC+BEMC+EEMC)

**** NOTE *** This sample cannot be used to verify beamline constraints.  It will contain positrons thrown at (x,y,z) into zerobias with VFMCE.

>>>> * throw single high energy electrons  as M-C signal event,
>>>> * test how multiple use of the same ZB events is handled (different M-C seed, different output file name)
>>>> * test the ZB event time stamp, event ID, run # is preserved
>>>> * test proper gains for BTOW & ETOW are used
>>>> * test reco electron energy agrees w/ thrown energy
>>>> * test chi2/dof for tracks is reasonable
>>>> * test dedx is reasonable
>>>> * test raw ADC for all BTOW & ETOW towers are stored in muDst
>>>> * test correlation between .geant and muDst events
>>>> * test timing , disk space

Agreed to put on hold with embedding team until technical issues are resolved.
