Variable x |
| Range of x |
| Description/Comment |
---|---|---|---|---|
luminosity |
| 0 < x |
| Requested luminosity will affect the event weight and in some cases the total number of events read out |
n_events_max |
| 0 < x |
| Maximum number of events to be read out, summed over all final states |
r_read_begin |
| 0<= x <= 1 |
| Fraction into the Point in file where readout begins, in units of the file's length; used to produce independent event samples |
r_read_end |
| 0<= r_read_begin < x <=1 |
| Fraction into the Point in file where readout ends, in units of the file's length |
pol_eminus |
| -1 <= x <= 1 |
| Electron polarization |
pol_eplus |
| -1 <= x <= 1 |
