run13 W embedding request for period 1 , <=day 126
1) 26runs have no ZeroBias daq files or have no ZB event.
2) 40 runs need more than one daq files.
3) Runs with very low luminosity which only requiry less than 10 ZB events are excluded.
4) Runs with test trigger ID are also excluded
Finally, the runlist for embedding with the ZB events requirement at the last three columns contains 1159 runs with totally 157880 events requirement(For W+ channel).
a) The numbers at the 3rd last column are the ZB events requirement for channels W+ --> e+mu and W+ --> tau + mu.
b) For W- --> e+mu and W- --> tau + mu channels, those numbers should be scaled by 0.32 from a), listed the 2nd to last column.
c) For Z --> ee channel, they should be scaled by 0.23 from from a), last column.
The required events are calculated beased on the luminosity weight of each run. Details can be found at slide 4 of this presentation.
Here is the link to the daq file list used for requiring daq files from HPSS.
Production: P14ia
Library: SL14a
Geometry: are based on the description at the STAR MC geometry page , should be "y2013_2".
Vertix distribution:
VertixX: sigma= 0.015cm
VertixY: sigma= 0.015cm
VertixZ: sigma= 42cm
Magnetic field: Reversed Full field.
