How to take a RICH pedestal run, generate the pedestal files and make them visible to the DAQ.

Take the RICH pedestal run

1. login as a-onl@adaql6 (or l7)

2. go to the directory: /adaqfs/home/a-onl/rich/pedestal

3. do the command: ./preped.sh

4. prescale all trigger except T3 and T5

5. run a standard calibration run in TwoArmRICH (comment as RICH pedestal), deadtime should be rather high (80-90%)

6. take at least 2000 events

Geenerate the pedestal files

7. login as adaq@adaql6 (or l7)

9. go to the directory: /adaqfs/home/adaq/e06010/rich/leftreplay

10. run analyzer

11. within analyzer do: .L newdecodeRICH.C+ (note: to speed up the processing, do not forget the + at the end)

12. then run: newdecodeRICH(####,2000,0,2) where #### = number of the pedestal run

Make them visible to the DAQ

13. go back a-onl@adaql2 in the directory /adaqfs/home/a-onl/rich/pedestal

14. do the command> ./copyped.sh
