Run event selection

For the selection of events one can refer to two kinds of numbers.

1. The sequence number of the event in the input stream
2. The event trigger number given once by online or GALEPH.

The first one is used on the cards NEVT and DEBU, the second one on SEVT.

• SEVT  

  Event selection card. The first number corresponds to the run number. Then, you can specify any number of events. If you want to specify a range, the upper limit must have a negative sign. This card has priority over SRUN and IRUN. You can have as many SEVT cards as you want.

  Example :

              SEVT  10 45 56 -70 101

  Events 45, 56 to 70 and 101 in run 10 will be reconstructed.

• SRUN  

  Run selection card. Here you can specify the run numbers you want to process. If you want to run in a specific range, the upper limit must have a negative sign. This card has priority over IRUN but will be ignored if you specify SEVT.

  Example :

              SRUN 1 -60 120

  Runs from 1 to 60 and run 120 will be reconstructed

• IRUN  

  Runs to ignore. Here you can specify the run numbers you don't want to process. If you want a specific a range, the upper limit must have a negative sign. This card will be ignored if you specify SEVT or SRUN.

  Example :

              IRUN 1 -60 120

  Runs from 1 to 60 and run 120 won't be reconstructed

• NEVT  

  Select a range of events according to the sequential number

  Example :

              NEVT  1 -50     ! Reconstruct the first 50 events
