pAu embedding

For pAu, two embeddings are needed for two production streams.

pAu 1, st_physics:
Standard Embedding request (particle in real events)
Particles: pi+, pi-, K+, K-, proton, anti-proton
Number of events: 50k each 
Real data: production_pAu200_2015, st_physics
Triggers: BHT1*VPDMB-30_nobsmd (500206)
Production chain: P17id
Library: SL17d
Particle per event: 1
VzTpc-VzVpd: (-6,6) cm, if VzVpd is saved in *.tags.root files.
VzTpc: (-6, 6) cm.
Phi: (0, 6.29) in radian flat
Eta: (-1, 1) flat
pT: (0, 15) GeV flat


pAu 2, st_ssdmb:
Standard Embedding request (particle in real events)
Particles: pi+, pi-, K+, K-, proton, anti-proton
Number of events: 50k each
Real Data: production_pAu200_2015, st_ssdmb  
Triggers:  VPDMB-5-ssd  (500001)   
Production chain: P17id
Library: SL17d
Particle per event: 1
VzTpc-VzVpd: (-6,6) cm if VzVpd is saved in *.tags.root files.
VzTpc: (-6, 6) cm.
Phi: (0, 6.29) in radian flat
Eta: (-1, 1) flat
pT: (0, 5) GeV flat
