Instruction for Offline Analysis of E93027
 

Filtering

1.  Go to /work/halla/e93027/filter

2.  setenv HALLA_DIR /work/halla/software

3.  Make sure that the data file is on the mss

         ls -ltr /mss/halla/e93027/raw

4.  Assuming step 3 is successful, then type

        bihan #### X

        where #### is the bare run number
         and X is the partition number

                    e.g.      bihan 1132 1      will filter e93027_1132.dat.1

5.  Notes -  As the run is being filtered, you can check the progress by
                     looking at the file /work/halla/e93027/filter/status_####
                -  Check the job status with jobstat -u all
                -  Once the job is complete, check the file SK_data####_X.log
                     (where #### and X are as above) to make sure the filtering
                    was successful.  If so, make the appropriate entry on the web
                   by editing http://www.jlab.org/~jones/e93027/anal_stat_q2168.html
 

Creating the Gep Ntuple

0. First make sure that you have set the following variables for instance in your .cshrc file:
 
setenv WORK /work/halla/e93027
setenv HALLA_DIR /work/halla/software
setenv HALLA_BIN $HALLA_DIR/bin
setenv LOC_HALLA_BIN $HALLA_BIN/$OSNAME
setenv PATH $LOC_HALLA_BIN/:$PATH
setenv LD_LIBRARY_PATH /usr/dt/lib

1.  Go to the directory /work/halla/e93027/replay

2.  Make sure that the run to be replayed has been filtered correctly,
     by verifying that the entry has been made on the web log (See step 5 above)

3.  Type:

    replay_gep #### X offline Y

       where:
          - #### is the bare run number
          - X is the partition number
          - Y is the number of the Q^2 point.

        e.g.      replay_gep 1132 1 offline 1

                            will replay e93027_1132_c.dat.1 with the espace kumac
                            fpp_offline.kumac using the header and cut files for Q^2
                            point number 1 (Q^2 = 2.168 (GeV/c)^2)

4.  Notes  - Check the job status with jobstat -u all
                 - This will create an hbook file with the Gep ntuple only !!!
